About the race
North Fork 50 takes place May 22, 2027 in Buffalo Creek, Colorado and offers two trail ultramarathon distances.
- 50 Mile
- 50K
Both courses run entirely on soft surfaces, predominantly singletrack with occasional double track. The route passes through ponderosa pine forest, sections burned in the 1996 Buffalo Creek fire, and areas with granite rock formations, providing varied terrain and open views. The 50 Mile lists about 6,425 feet of total elevation gain with a maximum elevation near 8,535 feet. The 50K lists about 3,670 feet of total elevation gain with a maximum elevation near 8,150 feet.
Aid stations are placed along each course; some locations supply hydration and food while an early station provides water only. Drop bags are available at the Buffalo aid station. Due to permitting changes, crew access is allowed at Buffalo aid only; crew must park inside Meadows Group Campground and walk to the aid station. Roadside parking is strictly prohibited and vehicles blocking roads may be fined or removed. Pacers are not allowed, but friends and family may run the final mile along Buffalo Creek Road with a runner.
Course markings use orange and black polka dot ribbons and orange pin flags; blue and white checkered ribbons indicate the wrong way. A finish line festival provides food and drinks for participants and volunteers, and all finishers receive a commemorative award. A portion of proceeds supports the North Fork Volunteer Fire Department; other beneficiaries listed include ProjectPurple.org and Conifer's StageDoor Theatre. Live split tracking is available for race weekend. Visit the organization's website for the most recent information.
