No better time to see Granby, CO than in the Fall! And in 2018 the ERS is making a weekend out of it... Join us Sept 22-23 as we launch the Snow Mountain Ranch Trail Running Festival. This 2 day event will feature the 6th Annual Snow Mtn Ranch Half Marathon, 10K, and 5K, PLUS see the addition of a 50K distance and Twilight 5K.   


The Snow Mountain Ranch Trail Running Festival will see NEW courses for ALL distances, BUT as always, keep the runners surrounded by the changing colors, rolling hills, and picturesque views,  making the location and courses still the  "Most Beautiful" on the ERS schedule.


The trail running festival will begin on Saturday with the 50K, 10K , and Twilight 5K. Followed by LIVE music, BBQ dinner, Beer Garden and Raffle Drawings. On Sunday, The Half Marathon and 5K will finish out the event weekend. 


Join us for any one of the races, and stay for the weekend, OR make it a weekend of racing and compete in multiple events over 2 days. Those runners that accept the challenge AND finish BOTH the 50K and Half Marathon distances will receive the Trail Running Festival's 

Inaugural "Moosehead Challenge Medal"

Special Race Note: The 50K is a 3 loop course, and can be run as an individual entry or as a team entry (team of 3), with each runner completing 1 loop of the course.

 "Snow Mountain Ranch has a couple nice gently rolling climbs, with a sunrise across the pond, grass range with a fall color backdrop, and golden aspen leaves falling and decorating the evergreens below. It's definitely the grand finale to the summer." - Stacy B. 

​​"It's not that I try to wish away the season, it's just that--hands-down--Snow Mtn Ranch is my favorite trail race of the whole series. It's the trail I look most forward to. "
