The lay of the land
The gravel race calendar in Colorado is busiest in September and June, with races most often in Boulder and Colorado Springs.
Gravel racing takes cycling off the pavement and onto mixed terrain — dirt roads, packed gravel, farm tracks, and the occasional stretch of asphalt. Race day is usually a mass start on a rural course, and the bunch shatters over the first climbs and rough sections.
Events range from short entry-level routes to 100+ mile epics, and aid stations sit farther apart than on the road, so riders are largely self-supported between them. Elite fields can be fast, but many riders are there for the challenge and the finish — the gravel scene is known for being welcoming to first-timers.
