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. Registration: 2024 – https://ultrasignup.com/register.aspx?did=111861
