The course starts and finishes in City Park beside Ferril Lake, heads west down Colfax Avenue (billed as one of America's longest commercial streets) past the State Capitol and Civic Center, ducks through Denver Fire Station No. 1, and follows the Cherry Creek and Platte River trails through Empower Fi +211m elevation
