_ The 2022 Boulderthon: Boulder Marathon & Half Marathon:
Run the first-ever Boulder Marathon and Half Marathon with a Downtown finish!
Running is the heartbeat of Boulder — one of the three hallmark recreational activities of the community (along with cycling and hiking, of course).
Together, run the streets & trails of Boulder, and serve as one of the great training grounds for Olympians, world-class athletes, and leisure runners alike. But despite running being hardwired into Boulder’s DNA — there is no signature, city marathon, until now- the first-ever downtown Boulder Marathon & Half Marathon: The Boulderthon.
