The Boulder Backroads

For decades, runners and walkers in Boulder County have enjoyed the beautiful scenery found on the Boulder backroads. With views of rolling farmland to the east and the majestic rocky mountains to the west, running on the Boulder backroads is always a memorable experience. For the serious athlete, the backroads are the perfect running surface – fast to run on, yet forgiving on the body – much less pounding than pavement. 

The Boulder Marathon is made possible by the cooperation and support of many City & County of Boulder employees. Including: City of Boulder; Boulder County Transportation Department; the City of Boulder Reservoir, (managed by Boulder Parks & Recreation); Boulder County Sheriff's Department; Boulder Police Department and the Colorado State Patrol.

We look forward to seeing you at the Boulder Marathon event on Sunday, September 19th, 2010 at the City of Boulder reservoir.
