HALF MARATHON

It’s fast, flat and shady - and with the amazing views of the Rocky Mountains, it’s no wonder Colfax is Denver’s favorite half marathon. Start and finish in City Park. Experience historic Colfax Avenue from the revitalized east Denver through historic downtown Aurora. You won’t want to miss the awesome run through Aurora’s Fire Station #1. Lots of firemen to cheer you on!
