Running in Colorado is its own sport. The air is thin, the weather flips on race morning, and the racing calendar is packed from the first spring 5K to the holiday fun runs in December.
Feat on the Street is a guide to running and racing the Front Range for the people who actually live and run here, plus anyone planning a running trip to Denver or Boulder.
No coaching hype. No “crush your PR.” Just a clear read on which races are worth your morning, what altitude really does to your pace, and how to train for the course in front of you.

Two things every Front Range runner learns
Altitude changes the math. Your sea-level pace doesn’t come with you to a mile up. For your first weeks here, run by effort and let the watch catch up to your legs.
The weather doesn’t read the forecast. A March start line can sit at 20°F and finish in sun. Dress for the start you’ll stand on, then shed.
Denver’s altitude changes how every race feels; pace by effort, not your sea-level numbers.
What this site is, and isn’t
Feat on the Street is a running resource, not a race company. We don’t host events or take registrations. We compile what’s worth knowing about running here and point you to the races and routes that genuinely exist, so you can spend your weekends running instead of researching.
