About the Rim Rock Marathon
Grand Junction's Rim Rock Marathon is defined by Colorado National Monument rather than city streets. The small field and dramatic road make it a scenic challenge first and a time trial second.
Course
The point-to-point route climbs Rim Rock Drive, rolls across the monument, and descends toward the Grand Valley. Sustained elevation change and altitude demand conservative early pacing.
Race-day weather
November can bring cold, sun, strong wind, or early snow at the monument's higher elevations. The descent may be noticeably warmer than the start.
