Ultramarathon 101
What is an ultra?
An ultra is any running event over a distance greater than the marathon (26 miles 385 yards). Ultras are run on trails, roads and track. Twenty-five years ago, most North American ultras were run on certified road courses. Today, most North American ultras are trail races.
Most ultras are run over set distances (from 50K to 3100 miles). The 50K is the most popular race distance today. Some ultras are run for set time periods (6 hours to 6 days or more); the winner in these races is the person who covers the greatest distance in the allotted time. These races are a unique mental challenge because running faster doesn't make the race end sooner.
Can Lake Ultra's SpecificsThe 50-mile course is one big loop around a beautiful lake. The route is mostly flat to rolling roads with four major climbs including locally famous Bopple Hill and Bare Hill, the last major climb. The 50 Km course is point-to-point over the final 31 miles of 50-mile route, including many scenic parts of the full loop and two major climbs, one of which is Bare Hill Road, is the biggest challenge. The 25 Km course is point-to-point over the final 14.5 miles of the 50 Mile route after running short out-and-back starting on and using South Lake road. Both distances include too many hills to be the easiest ultramarathon in the region; that honor goes to the BPAC 6 Hour Endurance Challenge (run as many miles as you can in six hours on a flat 3.25 mile loop). However, because the Can Lake 50 is a road race, it is significantly easier to finish than any of the area trail races of the same distance. And, you can look at the spectacular scenery without risking tripping on rocks and roots. |
Why run ultras?
Achievable Challenge
While it may not be possible to run much faster (say, a 2:20 marathon), it is possible to run longer and farther than you ever believed possible. A huge range of ultra race distances and types ensures you won’t run out of challenges.
Friendship and Camaraderie
The ultra world is a small world. You will know your competition; you can run in same race with national champions and world-class runners.
Every finisher is a winner
For many runners, finishing is the main goal -- which may explain the large number of races with extreme challenges (hills, mud, rocks, heat, cold, etc.).
Can Lake 50 Specifics50 Mile.Completing the Can Lake 50 is a spectacular "achievable challenge." The most popular distance is the full 50 miles, probably because running all the way around the lake is so satisfying. It is way cool to go down to Lakeshore Drive after finishing and look out at the lake and realize that you've just run around the whole thing. Finishing under the 12 hour time limit only requires a 14:20 per mile average pace... you don't need to be a fast runner to finish; you can walk all the hills and follow a run/walk strategy on the flatter sections and still easily finish within the time limit. If you think you might need more time (e.g., your flat road marathon times in the 5 hour range), please request an early start time. With a 6am start, you only have to average 15:30 per mile to finish before the 7pm time limit. 50K.The 50K is an even more "achievable challenge," ideal for a first ultra or for those years when your training is inadequate for a full fifty miler. If you are fit enough to finish a marathon in five hours, you should have no trouble finishing the 50K under the 9 hour time limit. Just walk all the hills and follow a run/walk strategy to average under 17:20 per mile. Age Graded Medals for Both RacesFor runners looking for a challenge beyond just completing the distance, the Can Lake 50 also gives every runner (male or female at any age) an equal chance to win to win a gold or silver medal. The Gold standard represents 65% of the World Masters Athletics (WMA) standard for each age. It's a tough but achievable performance. The Silver standard is significantly easier to achieve at 55% of the WMA standard for each age. Last year, approximately 5% of the 50 mile & 50K finishers received Gold medals and 30% received Silver medals. Bronze medals were awarded to the remainder of the field in both races. |
Ultras are Different
- Like marathons, aid stations have food & drink; but unlike marathons, the aid stations are farther apart. Most runners carry water bottles and some runners carry food.
- Ultras often go where there are no rest rooms. Carry your own toilet paper and be prepared to go in the woods. Carry your favorite anti-chaffing treatment (e.g., a small tube of Vaseline).
- Roads are open to traffic with limited road marshals. Route markings can be easy to miss and the markers are sometimes removed - which means runners are expected to be aware of the race route and take some responsibility for not getting lost.
- Weather conditions can change drastically during a long race. A cold morning can be followed by a hot afternoon. Rain storms may blow through. Drop bags transported by race personnel to aid stations can be used for rain gear, dry clothes and favorite food & drink.
- Some races allow runners to have a handler who meets them along the race route and provides aid, change of clothes, shoes, etc. In long road and trail events, runners often can have a pacer run with them for the last part of the race. Pacers can help keep runners safe and on course by being an extra set of eyes and ears.
Can Lake 50 SpecificsBe Prepared.You will be out on the road a long time and the aid stations are much farther apart than you would have in a big city marathon. You should carry the following items at a minimum:
You may want to have some of the following with you, especially if you've needed them in previous races:
Depending on the weather on race day, you may need to carry a rain jacket. You can also have drop bags transported to some of the aid stations. Aid StationsWhile the Can Lake 50 aid stations are relatively close together (from 2.8 to 4.9 miles apart), you should carry a water bottle and have it refilled at the aid stations. If you prefer to use a hydration pack, e.g., Camelbak, etc., be sure it can be quickly refilled. Aid stations will have water and GU Electrolyte Brew to refill your bottle and a cola drink in cups. Since the cola drink is carbonated, your best bet is to drink the cola while at the aid station. The aid stations also will have the usual ultramarathon snacks -- cookies, pretzels, bananas, etc. and GU Energy Gels or Chomps. You should test your equipment, food and drink on long runs prior to race day. If you find you need food or drink that won't be available at the aid stations, you will have to carry what you need and refill your pack from drop bags at 9.5, 20.6, 31.7 and 38.3 miles. (Or, have your handler transport these items for you.) If we have a cold day and/or rain is forecast, the aid stations will have extra large trash bags available to convert to emergency rain ponchos. (However, you are encouraged to carry a rain jacket, if needed). Rest RoomsThe inconvenient truth is that there probably won't be a rest room or porta-pottie around when you need to go. Carry toilet paper in a zip lock bag. You should be able to find a convenient tree or bush to get behind if you can't make it to one of the aid stations with proper facilities. Road MarkingThe course will be marked with spray paint on the pavement. Before each turn you will see a double set of arrows indicating the direction to turn. There will be another set of double arrows at the turn and a third set of double arrows after the turn to confirm you are on the correct road. The wrong roads will be marked with a big "X" after the missed turn. Regardless, runners are expected to be aware of the race route and take some responsibility for not getting lost. Only the last 10 miles of the course will be individually marked with miles-to-go designations. Course marking is on the left side of the road. These spray paint marks which are obvious to a runner are easy to miss when driving on the right-hand side of the road. Handlers and friends driving around the loop should use the maps and directions in the Race Handbook. Traffic & Road MarshalsAll of the roads on the race route will be open to traffic. Watch for traffic and be careful at all turns and road crossings. Late in the race when you are tired, remember to be extra careful as your judgment and reaction times will be impaired by fatigue. Road marshals will be at a few turns. Follow the directions of the road marshals. You may have to stop for a few seconds until the marshal says it is safe to proceed. HandlersMost runners rely on the aid stations for their needs. Optionally, a runner may have a personal handler and receive aid at any point along the course. Decide with your handler how frequently you want access to aid, e.g., every 2 or 3 miles. Have your handler drive ahead that distance and find a safe place to park on the right side of the road (or better yet, turn off on a side road to park completely off the race route). Your handler then can safely cross to the runner's side of the road and hand off drink or food when you come by. Tell your handler what you will want at the next handling point so he/she can have those items ready for you. Having a handler can be a big advantage if you need special food or drink or if the weather conditions are changeable. Toward the end of the race, your handler can also monitor the progress of other runners near you. Knowing that you are catching the runners ahead can be powerfully motivating late in the race. Tom's Tip: The best location to receive aid from your handler is at the bottom of a hill so you can walk while drinking and eating. Your handler should not stop on the road within 100 yards of the official aid stations to avoid traffic congestion and parking problems. PacersPacers are allowed for runners in either race after the Vine Valley Aid Station for the final 15 miles. Your pacer is not allowed to carry your bottles and other gear, i.e., cannot be a "mule." However, a pacer can help keep you safe and on course by being an extra set of eyes and ears. And, the right pacer can help you get through any bad patches... talking when you need to be distracted from your fatigue, being quiet when you need to concentrate on the task, telling you that you look good when you don't, etc. |
Training - From Marathon to Ultra
Modify your favorite marathon plan and make it specific to your target race:
- Go longer and slower on your long run
- Do your long run on terrain like the target race (hills if hills, trail if trail, etc.)
- Test your race food, drink, pack, etc. on long runs
- Test your walk routine on long runs
- Keep speed work in your plan (one day a week, repeat miles or tempo runs)
bullet - Make easy days even easier than in the marathon plan
- Take long, brisk walks on recovery / cross training days (the active recovery can be better than doing nothing and the walking is actually race-specific training for most of us)
Can Lake 50 SpecificsWhen to Start TrainingMost ultra and marathon training plans call for a 24-week buildup:
Training Plans for First UltrasSince the Can Lake 50 is a road ultra, the training requirements are similar to those for a marathon. If you have a marathon training plan that has worked well for you in the past, then base your training for a first ultra on that plan. The Jeff Galloway Marathon Plan (with some modifications described here) is an especially good choice for mid-pack runners and lower mileage trainers. Faster runners and high mileage trainers, especially folks with lots of sub-3:30 marathon experience, might want to look at other plans, e.g., Jack Daniels, Hal Higdon, etc. See Additional Resources for some example plans. Several key elements make the Galloway plans a good fit for ultra training:
How do you get a Galloway marathon plan for little money? Go to your Public Library and check out Marathon: You Can Do It! (Jeff Galloway, copyright 2001). If you can't find the book or want to own a copy, be sure to get the 2010 Revised Edition from your local book store or online retailer. There's even a Kindle e-book version for about $10. The book has plans for marathon time goals from 4:40 to 2:39, a range which will cover most runners. Here's an example 3-week cycle from a Galloway plan (2001 edition) Galloway Plan for 4:20 Marathon Time Goal (weeks 15-17)
To get started with a Galloway plan, read the book. Sign up and run a local 5K if you haven't run one recently. Look up your predicted marathon time (the table is in the Appendices at the end of the book). Start with the marathon plan that is the closest match to your predicted time. (Note that Galloway plans assume a full six month buildup to the target race. If you already have a solid base and you have less than six months before your ultra, you can skip some of the initial weeks in the published plan.) For another view on moving up from the marathon to an ultra, click here for an article from Marathon & Beyond. The author is famous for his successful ultras done with limited training mileage. Plan Modifications for 50KBecause it is run on a road course, the Can Lake 50K is basically a longer marathon with some big hills. Modify your favorite marathon training plan (see previous section) to include the following:
Keep in mind that the most important part of running hilly terrain is to train your legs for the downhills. Review the course description and pay attention to the leg profiles. Use this information to plan your training runs. Plan Modifications for 50-MileWhile the 50K is basically just a longer marathon, the 50 mile is a different animal requiring significantly more endurance. The following table shows the Galloway plan modified to train for the Can Lake 50 Mile. Galloway Plan for 4:20 Marathon Goal Time (weeks 15-17) - Modified to Train for 50 Miles at Can Lake 50
Notice that the modified plan shifts the workouts so that 50% or more of the week's mileage is concentrated in back-to-back runs on the weekend. This shift helps build endurance. However, this shift also increases the risk of injury and potential for excessive fatigue, so it is important that the weekday runs and cross training is kept under control. The runner should do no more than what is called for in the schedule and, if fatigued, feel free to take an extra day or two off. The 50-Mile training plan should include the following:
Keep in mind that the most important part of running hilly terrain is to train your legs for the downhills. Review the course description and pay attention to the leg profiles. Use this information to plan your training runs. Predicted Race TimesUse shorter races to get a predicted marathon time (and provide some needed additional speed work). These races can be 5K, 5-mile, 10K or even 15K. Calculators are available on the web to give equivalent times at standard race distances. Here's the one at the Marathon Guide web site: http://www.marathonguide.com/fitnesscalcs/predictcalc.cfm Galloway added an even simpler alternative in his 2010 Revised Edition of Marathon: You Can Do It! Step 1: Run a one mile time trial. Step 2: Multiply your time in seconds by 1.3 for your predicted pace for a very hard effort marathon. For example, you run the mile time trial in 7:00. That time is 7 x 60 = 420 seconds. Multiply by 1.3 and you get 546 seconds. Divide by 60 and you get 9:06 for your predicted marathon pace and a predicted marathon time of about 3:58. Add 2 minutes to the predicted marathon pace in this example and you should do your long runs no faster than 11:06 per mile (including walk breaks). Repeat MilesRepeat miles and timed miles can be done on any reasonably flat road if you use a Speed Distance Monitor. I use a Garmin 210. I set it up to automatically record laps at every mile and display the Average Lap Pace. After a warm up, I hit the Lap button and start the first mile, periodically checking the displayed Average Lap Pace. If the pace is too fast or too slow, I make speed adjustments. At one mile, the GPS automatically records the lap and I start the jog recovery. When ready for the next mile, I hit the Lap button again. After the last repeat mile, I cool down. Later, at home, I review the History of the run. The repeat miles are easy enough to sort out from the other laps. Using a Heart Rate MonitorIf you are interested in training with a heart rate monitor, Galloway includes a chapter on the basics in both editions of Marathon: You Can Do It! For the ultrarunner, a heart rate monitor is most useful as an aid in correct pacing. Monitoring your pulse rate, especially in the first couple of miles of a run, will help you control the impulse to run too fast on easy days or to start too fast in races. In hilly races, a heart rate monitor is a great aid for learning how to slow down enough on hills to avoid going into the "red zone." For races with hills, think Even Effort instead of Even Pace. Slow down on the hills so your heart rate and perceived effort don't increase much over what you were doing on the flat approaching the hill. If you try to maintain the same pace up the hill, you will have to slow after the hill to recover. For a more advanced text on heart rate based training, see Additional Resources. Avoid these common errors!The most common errors in using a modified Galloway Plan (or any other plan) involve doing too much, too soon and/or too hard, such as...
My experience is that these errors have a cumulative effect. Initially, you feel good doing more -- but as the weeks go by, the long run and repeat-mile workouts get harder and harder to complete because of inadequate recovery. The obvious answer is to follow the plan. Keep a Training LogRunners who log their runs are more likely to stick to their training plans and achieve their goals. Logs come in many forms… you can just use that extra paper calendar you got in the mail or you can create a spread sheet in Excel. They still sell running log books at Barnes & Noble and on Amazon if you want something with more heft. And there are free and almost free online logs. If you have a Garmin GPS watch, you can use Garmin Connect. Uploading workouts is quick and easy. The goals and reporting features are powerful and easy to use (e.g., tracking miles each week or for the year). One issue for me is that I have not found an easy way to back up my data for more than one page of activities at a time. Another is that the social media features are not well integrated. |
Running the Race – Have a Plan and Follow It
Following a plan takes discipline, but doing so is your key to a successful race. As you make your plan, keep these points in mind:
- Some elite athletes can run strongly for every step of an ultramarathon, even running all of the climbs on a hilly course.
- Ordinary runners, who would otherwise have difficulty finishing, can do the extraordinary in ultramarathons by the simple strategy of mixing running with short walking breaks. This strategy has been demonstrated to double or triple the distance that a runner can complete compared to non-stop running.
- The run/walk strategy is not just for the slow runner seeking only to finish. Fast times can be run and races won with a run/walk strategy. My own Personal Bests were all set using a planned run/walk strategy: 50 miles in 6:21; 100K in 8:00, 78+ miles for 12 hours; 128+ miles for 24 hours.
- The walk segment needs to be long enough to eat and drink, give the running muscles a break and recover a bit. Short, frequent walks work better for most, e.g., walk 40-60 seconds at end of each run segment.
- The longer the race, the shorter the run segment should be. The fitter the runner, the longer the run segment can be. When I was a reasonably fit open runner, my run segments would be 2 to 2.5 miles for 50 mile and 100K races and 1 mile for the 12 hour and 24 hour. As a less fit super veteran runner, my run segments are now 1 mile or less for the 50K and 6 hour.
- Have reasonable expectations – start at a sustainable running pace and run/walk strategy. Ultras are not won in the first 20 miles. Your goal for a 50K or 50 mile should be to maintain the same run/walk strategy for the whole race with only a slight slowing of your running pace as you get tired.
- Include scheduled walks from the start on flat courses. Also, include scheduled walks in any long flat sections of a course with hills. As most ultras do not have every mile marked, it makes sense to use time to schedule walks. For example, run 10-15 minutes, walk 40-60 seconds.
- Walk all hills from the start on hilly courses. If a hill seems too easy to walk all of it, alternate running and walking (e.g., run 100 meters, walk 50 meters, repeat to the top). If the gradient changes, do your run segments on the easier bits and walk the harder bits.
- Eat and drink while walking (carry a water bottle and food). Carry two water bottles on hot days or if the distance between aid stations is more than an hour.
- Spend as little time as possible in the aid stations. Treat them like a NASCAR pit stop. Decide what you want before you get to the aid station. Pull in, give your bottle to a volunteer to be refilled, grab something to eat and walk out of the aid station as soon as you have your bottle back.
- When things go wrong, fix them quickly. Eat if you are starting to bonk. Take an electrolyte capsule if you are starting to cramp. Fix your feet if you are starting to blister, apply Vaseline if you are starting to chaff, and so on.
- The hardest part of an ultra is often the middle miles or even getting to halfway. It is easy to get freaked out by the distance or time remaining. Don’t think about how many miles or hours remain. Take the distance one chunk at a time. Just think about getting to the next aid station, getting to the next walk break, getting to the top of the next hill, getting to the next power pole.
- Maintain relentless forward progress until you finish.

Food and Drink
Ultras are too long to be run on just plain water. Most of the calories needed to finish an ultra come from stored fat but some carbohydrates need to be replaced each hour to avoid bonking (hitting the wall). Many runners find it helpful to also replace electrolytes.
- 50 grams per hour is a bare minimum target for carbohydrate replacement for average runners. That's a minimum of 200 calories from carbohydrates in food and fluids consumed each hour.
- Drinking to thirst works well for most runners. Carry a 16-20 ounce bottle with water or a sports drink and drink to thirst each time you take a walk break.
- Short ultras can be done on fluids and gels, especially if you are both fit and fast.
- Some runners get good results with bananas, defizzed Coke and GatorAde despite the high fructose content.
- Real food is often eaten in longer ultras.
- Some runners use liquid foods like Ensure or specialty products like GU Roctane.
- Experiment and find what works for you. Bring your own favorite foods and drinks to the race. Put supplies in drop bags or set up your own mini-aid station at the Start/Finish on loop courses.
- Sometimes your stomach will rebel at foods that worked before. When what worked before stops working, try something else. At times like that, the appropriate food is anything you can tolerate.
For more information, see Additional Resources.
Can Lake 50 SpecificsFluidsThe Can Lake 50 aid stations will have water, GU Electrolyte Brew and a cola drink. You should test GU Electrolyte Brew on training runs. Your local running store may have the product or you can order it from GU Energy Labs. The cola drink will be carbonated so you should plan to drink it at the aid station (i.e., don't fill your bottle with it). If you find you need fluids that we won't have at the aid stations, you will need to have a handler or use drop bags. The drop bag locations are 10-12 miles apart. Two bottles supplemented by water at the aid stations will be enough to get you to the next drop bag to pick up another two bottles with your favorite fluid. FoodThe Can Lake 50 aid stations will have GU Energy Gel packets, cookies, potato chips, M & M's, and at select stations: GU Chomps, PB&J sandwiches, fruit and salt potatoes. You should test GU Energy Gel, GU Chomps and other foods on your training runs. If you local running store doesn't have the GU products, you can order them from GU Energy Labs. If you want something different to eat, you will need to have a handler or use drop bags. Carry enough of your favorite snacks to get you to the next drop bag location where you can refill your pack. |
At the Finish
- Check the posted results. Be sure to pickup your medal at the Finish before you leave
- Eat and drink some within an hour of finishing. It will help your recovery.
- You may not be in shape for a long drive after finishing a hard ultra... legs will be sore and you will be tired. Have someone drive you home or plan an overnight stay.
Post-Race Recovery
- If your legs are sore (it hurts to run), then don’t resume running until you are pretty much free of pain. Typically this takes 3-4 days if you have, for instance, trashed your quads.
- While your legs hurt, do something else for active recovery. Walk if you can do that with tolerable pain or ride a bike. Avoid impact exercise until the legs stop hurting.
- When you can resume running, go easy and give your body a chance to repair any lingering damage.
- As you resume training, you should find your short runs will feel good within a week or two at most. You may even be able to run a decent 5K after two weeks recovery.
- If you try a long run only a couple weeks after a hard ultra, you will probably feel very tired and sluggish after 10-15 miles. I have found my endurance comes back slower after an ultra than my short race speed (what little speed I have, anyway). It usually takes about 4 weeks before a long run feels comfortable.
- Allow 3-6 months between ultras to 1) adequately recover and 2) adequately train for the next race. The longer the race and the harder the effort, the longer the gap between races should be for optimal performance.
Can Lake 50 SpecificsIf your quads are sore and you have to go down stairs backwards, the downhills on the course beat you up. Wait until you are pain free to resume running. |

Online Training Plans
In addition to the training plans described previously, there are many other training plans available on the internet, including some specifically for ultramarathons.
- Santa Clarita Runners Ultra Schedule. The Santa Clarita Runners in California have an online application that will generate a training schedule for you. You enter the date of your race and select the distance (either 50K or 50 Miles). The application returns a table with daily workouts from the current date to race day. The table can be downloaded as an Excel spreadsheet. The Santa Clarita schedule is a one-size-fits-all approach, i.e., no personalization for your level of fitness. There's no advice on pacing the training runs and no speed work in the plan. Distance is the only thing that changes day to day. The Santa Clarita Runners plan is at www.scrunners.org/ultrasch.php.

Part I: History of fluid intake during exercise and the evolution of the sports drink industry
Part II: Why dehydration does NOT CAUSE heat stroke
Part III: Drinking to thirst - what we learn from research in the field and elite athletes
Part IV: Why DRINKING to thirst is the optimal way to drink
Part V: Do sports drinks really help prevent electrolyte loss, dehydration and impaired performance? - Sports Scientists Series on Muscle Cramps (www.sportsscientists.com/2007/11/sports-drinks-sweat-and-electrolytes.html). Putting it all together, here's the key concluding quote from the series: "So bottom line - drink to thirst, don't worry too much about what you drink, but just make sure you are getting enough ENERGY in - the one thing that the sports drinks provide that is required is glucose, and so plain water is unlikely to be sufficient for longer than about 2 hours of exercise."
