The third stop on the Big Mountain Enduro Series, and fourth stop on the North American Enduro Series, took over Keystone Bike Park last weekend. The race contained six stages of some of the most rugged lift-accessed mountain biking in the country, complete with rock gardens, drops and high-speed features.
The race wrapped up with Nate Hills taking the pro men's field by a large margin, followed by Kyle Warner, Marco Osborne, Mason Bond and Jeremy Horgan-Kobelski.
On the women's side, Heather Irmiger took the race after holding a strong lead all weekend. Brittany Clawson, Margaret Gregory, Cait Dmitriew and Rachel Throop followed Irmiger to round out the top five spots of the women's pro category.
