Several roads will be closed to traffic this weekend, as the Colfax Marathon gears up to take place in Denver for its 15th year.

"Originally created by the cities of Denver, Lakewood, and Aurora to recognize Colfax Avenue, the longest main street in America, it’s Denver’s only marathon. The race has grown to be a nationally recognized event, featuring unique courses incorporating the iconic landmarks of the Mile High City," the event description reads.
