Run a Marathon or Half in the Happiest City in the US! The Boulderthon is Boulder’s Only Downtown Marathon & Half Marathon with a post-race party on the Bricks!
Start at the beautiful Boulder Reservoir, and finish on Pearl St, Downtown, with sweeping views of the Flatirons throughout. The 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.
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 Boulderthon™ was born.

The race route is very boring. Expo is non-existent. I didn’t even get my bib. They gave me a replacement and then I never got an official time. I cannot recommend this race until they make some major improvements.
Best Marathon I Have Ever Run

Well Done. I’ve run nearly 50 marathons and/or half marathons and this ranks among the very best. Race day execution was flawless and I echo the previous comments about the professional staff and well organized volunteers groups. Looking forward to next year already!

It was brutally tough. There was a ton of elevation change throughout which kicked my booty, even living here it was rough. The start was late and the race directors had each corral go in waves, which was never communicated before. There were not enough bathrooms at the start. The live tracking didn’t work for spectators. The end of race snacks and goodies were not advertised well, which was a huge bummer. Overall, I wouldn’t do the race again but am proud that I completed it.
