Urban 10 Miler

Run the final 10 miles of the Colfax Marathon course!  The Urban 10 Miler features an epic run-through Empower Field at Mile High, downtown Denver, Confluence and Cherry Creek, 17th Avenue to City Park.  Sleep in, because you get a later start time – and it’s a staggered start from Rocky Mountain College of Arts and Design (RMCAD), filtering runners one by one into the ongoing marathon.  If you’re looking for a challenge at a shorter distance, this is the race for you.
