Course Map: Boulder Backroads Half Marathon

Runners follow an out-and-back course for the Boulder Backroads Half Marathon that unfolds along a gradual uphill ascent over the first half of the race and an equally gradual downhill descent in the second half. The starting and finish line lies at the Boulder Reservoir, just off North 51st Street – the same as the race location used in the annual Boulder Spring Half Marathon – and runners follow a figure-eight-shaped route out toward the half-way turnaround point on North 41st Street.
