Iconic events
Colorado’s road-cycling calendar is stacked: the Triple Bypass (three big passes in a day), the multi-day Ride the Rockies, and the Copper Triangle near Copper Mountain. Many sell out early.
Riding safely at altitude
The climbs are long and the air is thin, so pace yourself, hydrate constantly, and fuel more than you would at sea level. Storms build most afternoons — start early and be off the high passes by noon. Most high routes are snow-free roughly late May through October. Gear up with our gear guides, and note many of these roads are also our favorite scenic drives.
