RMCC Peak-to-Peak Brevet 300km
Classic 300km road brevet from Louisville over Coal Creek Canyon to the Peak-to-Peak Highway, Allenspark, and Glen Haven — front range randonneuring at its best.
The vibe
Coal Creek to peak-to-peak highway
The Peak-to-Peak Highway is one of Colorado’s most celebrated road cycling corridors — high, scenic, and strung between mountain towns that feel genuinely removed from the Front Range sprawl. RMCC’s 300km brevet uses it as the centerpiece of a dawn-to-dusk (and then some) mountain journey, climbing Coal Creek Canyon from Louisville to reach the highway before continuing through Allenspark and descending Glen Haven into Big Thompson Canyon for the return.
300km puts this firmly in ultra-distance territory — a long day by any measure, and longer if you’re stopping at the controls and managing your pace carefully across 12-plus hours of riding. The elevation profile is substantial: Coal Creek alone is a significant climb, and the highway section runs at altitude before the descent. August timing is calculated to get the best chance of stable weather, though afternoon thunderstorms are always possible.
Free to enter in 2026. RMCC and RUSA membership required. Sign in at 4:00 AM, departure at 5:00 AM. Lights required for the predawn start. The ride is self-supported between controls — bring food, tools, and the ability to handle roadside mechanicals. Full route and control information at rmccrides.com.
