More Than 50,000 Run the 2016 Bolder Boulder 10K

The 38th running of the Bolder Boulder 10K—one of Competitor’s must-do 10Ks—drew an estimated 50,765 participants to the streets of Boulder, Colo., on Monday in a celebration of fitness, fresh air and Memorial Day. The race is one of the fastest and deepest in the country—more than 500 runners broke 40 minutes this year—but it has a community atmosphere with bands, belly dancers, costumed runners, Slip ‘n’ Slides and unofficial aid stations with beer, bacon and cupcakes. Brandon Johnson, 28, of Denver won the citizen’s race title in 30:34, while Boulder’s Melissa Doc, 34, was the top women’s finisher in the open race in 35:44. In the pro races that capped off the day, Kenya’s Isaac Mukundi was the top finisher in 29:12, while Ethiopia’s Amane Gobena was the top woman in 33:39.
