Boulderthon: Inaugural Downtown Edition

Running is the heartbeat of Boulder — one of the three hallmark recreational activities of our community (along with cycling and hiking, of course).Together, we run the streets & trails of Boulder and serve as one of the great training grounds for Olympians, world-class athletes, and leisure runners alike. We are so grateful & proud to have the world’s best 10k — but despite running being hardwired into Boulder’s DNA — we have no signature city marathon.
This was the question we asked everyone — and we couldn’t find out why.
In one of the great health meccas of the US, rated one of the healthiest, happiest cities in the country, we couldn’t find a premier long-distance marathon.
After years in the making and the opportunity to acquire a 19-year-old race series, the Boulder Backroads Marathon & Half Marathon, we knew the time was now. As residents of Boulder County and local business owners, our goal from day 1 has been to create an inspiring, community-driven marathon series to serve as the premier fall race in the state. We decided to create the epic, downtown marathon race the beautiful city and community of Boulder deserves.
The race starts at the beautiful Boulder Reservoir, and finish on Pearl St, Downtown, with sweeping views of the Flatirons throughout. Our Full and Half Marathon will run through County farmland before finishing in a first-of-its-kind, epic finish at the heart and soul of downtown Boulder.
