About the Run Rabbit Run 100 Mile
This independent Colorado mountain race has grown into a competitive 100-miler while retaining distinct starts for elite Hares and broader-field Tortoises.
Course
The mountain loop uses Routt National Forest trail around Steamboat Springs. Sustained climbs, altitude, technical descent, and a full night out reward conservative early pacing.
Race-day weather
September may deliver warm sun, freezing overnight temperatures, rain, or early snow. High-country exposure makes spare layers important.
