The lay of the land
The road cycling race calendar in Colorado is busiest in August, September, and December, with races most often in Colorado Springs, Boulder, and Denver.
Road cycling events cover a wide range of formats — from non-competitive gran fondos and century rides to closed-course criteriums, time trials, and road races. What they share is sustained effort over a long distance on a bike, usually on paved roads.
Many events offer several distance options at the same venue, so you can pick the route that matches you. Beginner-friendly gran fondos make a welcoming entry point.
