Hey! Some tips that helped me on my first ultra(at 16 y.o.): 1. gradually ramp up your mileage as the weeks go by and maybe 4-5 weeks out, try a good long run of 17-26 miles. Something to get you an idea of what going beyond a half marathon is like. I didn’t train whatsoever for my ultra(don’t recommend), but I come from a family of ultra runners, and this is generally what they do. 2. Food choices…What tastes good at mile 8 may be horrific at mile 27. As you run, nutrition is key, but make sure to eat what will stay down. Sometimes longer distances can mess with this stuff! Don’t try any new foods either on race day bc you don’t know how they will affect you late into a race. 3. Choose a pace that is steady and maintainable. Don’t start too fast- that could make you bonk later. If you don’t care about time, you could even hike up parts that you don’t want to run! Whatever makes you comfortable and keeps you moving forward is what matters. 4. Shoes are very important to decide on for the race, and be sure to break them in before hand. You don’t have to have the latest and greatest shoe, but do be sure that your chosen pair has enough cushion, support, etc. That’s all I can think of for now! Don’t be worried about your age at all- if you train, fuel properly, and pace yourself, you will have a super fun time! The ultra community is very supportive of young runners, so I’m sure everyone will be cheering you on!


Go slow, take it easy, enjoy the ride. That applies to training, too. Be realistic about the fact that your whole life is ahead of you, and if the process is causing pain, try again in a year or two. You’re not too young, just be smart. :) Get a copy of Relentless Forward Progress and enjoy!


Thank you and everyone else for the advice, I just bought a copy of the book and I’m beginning my training today!


Hooray!! Best of luck to you!


Im also 17! In september 2021 i ran my first road marathon and im also planning on running a 85km trail race My goal will just be to finish and eat and drink enough I think ass long as you train well its doable!


Look up Lucy Bartholemew :) Have fun!


Run slow enough to be able to talk. If you are not able to talk then you are running to fast. Experienced partner and pacemaker for whole race is worth in gold. 50km is hell of a distance especially if day will be warm. It's better to finish with feeling that you could do it faster than not finishing at all due to exhaust and cramps in muscles.


It's fine. In the UK the Scouts put on a race called the 4 Inns. The format has recently changed but it's been running for at least 30 years as I (and many others) did it when I was 16. It's 68km with 2,200m of vert.


Awesome! I'll tag along with what most people are saying here. Be honest with yourself as your train. Listen to your body's warnings and heed them. Even aged runners sometimes are not ready for an ultra due to extenuating circumstances (or sometimes it feels like the planets are just not aligned right /s). Run today so you can run tomorrow: don't injure yourself because you were afraid or injuring your ego. Your ego heals faster than your physical body.


It will be as safe as any other race provided you train for it properly. Sept 10 is less than 3.5 months from now. In theory, you should already be a couple of weeks into your training and hopefully had a base of about 35 miles per week over the last couple of months going into it.


Can you do it, certainly. But please consider 1. Your body is still developing and 2. Long term burn out I'm not a scientist, but I'm sure there are plenty that would weigh in on any long term effects. What I will say is that I've seen a lot of people fall out of love.with running from overtraining. Personally id say you should enjoy your time with a cc team if that is an option, because you'll never get that chance again. All that said, if you make the decision, go get it!


u/mini_apple has the best advise. Yonni Kepes, who was youngest known New Zealander to complete a 100-mile ultra marathon, might also be a helpful example for you: [https://www.stuff.co.nz/the-press/sport/104295468/marathon-effort-from-waipara-teen-yonni-kepes](https://www.stuff.co.nz/the-press/sport/104295468/marathon-effort-from-waipara-teen-yonni-kepes)


That guy is amazing


Check the race admission criteria. In the UK, (Rule T3 (141) S5 UKA Trail Running) gives a minimum age of 20 that is applied to a lot of long distance trail events. They have other categories with different age limits, but for trail running, under 18 the limit is 25k & under 20 the limit is 45k. http://www.uka.org.uk/wp-content/uploads/2021/05/UKA-Rules-for-Competition-2020-2022-Incorporating-World-Athletics-Rules-Updated-May-2021.pdf


It's fantastic that the sport has younger people like yourself interested, that's so great! And to see other young runners here too is amazing. Our sport is in a great spot! If you have the means to work with a running coach, it can be a huge boon to your running. I wish I would have done it sooner in my running career. So being so young, if you can work with someone now, you will have a great opportunity to build an amazing base of talent and knowledge :) Some great advice in here as well if you can't, but I always say at least look into it :) Also, I write a trail running newsletter and am putting an article together right now that I'm looking to other trail runners for their two best piece of advice. If anyone wants to help out with that, shoot me a message


You may be interested in [this video](https://youtu.be/wU50KWPTb_s) of a 16 year old who has run multiple ultras. I started running longer distances on the backroads near my home when I was 12-13 before starting high school cross country at 14 and getting my first formal training. The positive impact during that developmental phase carries through into one's adult life provided you're getting adequate & quality nutrition. As far as getting injured, it's part of being a runner regardless of one's age. It's unavoidable for marathon and longer distances. Learning how to minimize and recover from injury is a key part of our sport.


The nutrition and pacing really have a ton to do with the course profile. A very hilly 50km could take 8 hours and involve ultra-style pacing and nutrition (go slower than you feel capable of, bring a variety of foods that are salty/sweet/savory), but a flat road 50k can be approached like a marathon: eat gels and water, run a little slower than marathon pace. You're young so don't go too hard on mileage and don't increase too fast. If you're reaching for higher weekly mileage, I recommend adding mileage every 4 weeks, about one mile per run per week. 6 runs a week = add 6 miles every 4 weeks.
