Pigtails Challenge 50k | 100k | 100 Mile | 150 Mile | 200 Mile

May 28 - May 31

|Recurring Event (See all)

An event every year that begins at 12:00 am on day fourth of May, repeating until May 22, 2025

The Pigtails Challenge takes place at Lake Youngs Watershed which is a rolling loop with 900 feet of elevation gain per loop. While this is not considered a technical mountain race, however don’t be fooled, 900ft per loop adds up considerably ( ex. 100 milers do 10 loops x 900ft= 9,000ft vertical) This is an excellent course for those wishing to train in a very well supported race. If you’re looking to attempt a new and longer distance, such as a first 100 miler, register now. For hardcore types who want take a bite at a longer distance such as 150 or 200 miler and test their mental fortitude, this is the perfect race. Since this is a loop course, the option to throw in the towel always looms in the background. It will test your perseverance to carry on lap after lap when you could easily call it a day, pop blisters, get warm, eat and have a beer. For those wanting to do a shorter distance we started a 50k to the lineup in 2016, one 3 mile loop and 3 9.4 mile loops.

This is a multi-use trail which includes walkers, bikers, horses, etc. Please share the trail. With horses, it is not a good idea to surprise them. If you are coming from behind, make some noise to let the rider know you are coming. Also, slow to a walk when you pass them.

This is a well groomed (with a few rougher spots) 9.4 mile double track loop trail. Once on the trail, run slight uphill for short distance (1/8 of a mile) to a T in the trail. You will see a chain linked fence. We will have a sign there pointing to the left for odd loops. Turn left (now fence is on your right). Follow trail and fence around entire loop. At no point do you cross a road. There will be a break in the fence and a short asphalt section at about two miles going this direction for about 20 yards. Just run straight across and reconnect with the trail. The 200 milers will run 21 loops with an extra out and back on the trail at the start (1.3 out, 1.3 back). The 150 milers will run 16 loops and their first loop will be shortened slightly (I will walk you in about 1/4 mile on the trail where you will start). The 100 milers will run 10 loops with 6 miles at the start (3 out, 3 back) to make that distance. The 100K runners will do the out and back with the 100 milers then do 6 full loops. The 50K runners will run 3 loops with 3 miles at the start (1.5 out, 1.5 back) to make that distance. The out and backs will be in the clockwise direction before running the full loops starting in the clockwise direction. All distances are certified.
Please let the timer at the start/finish know that you have arrived at the end of each loop so that we can keep track. If you want
