The article below was written by Matt Sims of the Rock/Creek Race Team. Registration for the 2012 Rock/Creek StumpJump 50k is now open; the race takes place on Saturday, October 6.

Training for a 50k takes time and devotion to the sport of running. It is a landmark in many people’s running careers, and merely a stepping stone for others. People ask me all the time whether or not the Rock/Creek StumpJump 50k race is a good first 50k. My response is that any 50k is a good first-time 50k. There are obviously some 50k races that have easier terrain or fewer hills, but doing the 50k is not the hard part; training for the 50k is the hard part.
If you are reading this, you have some interest in breaking into the next level. Many of you are thinking to yourselves, “Why am I considering a 50k when I haven’t even run my first marathon?” The marathon has such a stigma attached to it, that in many ways I consider training for a 50k much easier. A 50k trail run is merely a long day in the woods. When one approaches the 50k with that attitude, the distance is made simple and more fun.
Base Mileage: If you are considering the 50k distance, you should first have a runner’s base. If you can answer yes to the 3 questions below you can complete your first 50k.
1. Do you run 3-4 days a week?
2. Have you been running consistently for 2 years or more?
3. Can you run 10 miles non-stop?
Training: I feel like training for a 50k properly takes 3 months. The schedule below should provide a guideline of training for the Rock/Creek StumpJump in October. Our training begins July 1st.

OCTOBER TAPER
The 8-9 days before the race should consist of no more than 3 days running with no more than 30 minutes each run.
Nutrition is as important as the training, often overlooked and underestimated.
1. Take in 16 ounces of fluid for every hour of running.
2. For every run that lasts longer than 90 minutes, replace electrolytes with a sports drink such as Hammer Nutrition’s HEED. Be sure to avoid drinks with high fructose corn syrup and other simple sugars. Hammer’s Endurolyte Electrolyte Replacement Capsules are also a quick way to replace electrolytes on your runs.
Remember that fluid replacement is not necessary to complete the training run, however it aids in recovery so that your body is able to run again the next day.
While on long training runs, I like to take in solid foods. Some of my favorites are PROBAR, Balance Bars, bananas or pretzels. These are also good to eat during training because most 50k runs offer these types of foods at aid stations during the race.
TRAIL or ROAD
With all the training you will do, it is realistic to expect 80% of all runs to be done on the road. Try to do runs over 3 hours on the trail. Your familiarity with trail footing and undulating terrain will give you the confidence you need for race day. For these 3 training months, play close attention to your body. Buy new running shoes, back off the distances if you feel an injury coming on, and feel free to modify the schedule to suit your needs.
If you can stay on course for these 3 months, you will cross the finish line of the Rock/Creek StumpJump 50k trail race, and what a great first 50k experience you will have had!

Is this race full for 2011? I cannot find anything definite, on the internet, telling me if they haves stopped taking applications, but I cannot find an entry form either. Please advise, as I am REALLY anxious to run my first Ultra and this would be the perfect race for me,
Many Thanks!

Hi, I am doing my first 50k and in May 12′ I really like the looks of this plan, and it’s a 16 week plan which works perfect. I also like the going by time instead of mileage.
Can you elaborate more on the OCTOBER training? I know you have to taper but what does the rest of october look like before the taper? When do you do your last long run?
Thanks,
Adam

Adam,
StumpJump 50k is traditionally the first weekend in October, so your last long run would be about a week before the race. Some years, like in 2011 when the race was on Oct 1, you’d have to cut back in the 4th week of September to get your training in. This year’s race is October 6, so you might want to skip your long run on the preceding Saturday to get your taper in.
Hope that helps!

Thanks Jeff,
I am actually not doing stumpjump 50k. I signed up for Pineland Farms 50k in Maine, which is on May 27th. But this training schedule will work perfect for me, if I break it down to a 16 week training program. I will officially start training on Feb. 6th. I guess will start cutting back two weeks before the race.
Thanks!
