  This year, we're adding to the festivities with a Kids Activity Village that will include:

  Jeffco Library-sponsored yard games

  Sidewalk Chalk Art

  Emergency Vehicle Tours

  Bounce House and Inflatable Slide

  This family friendly event begins and ends on the track at the North Area Athletic Complex (NAAC) in Arvada with a scenic trek along the Fairmount Trail in the middle. Following the 5K there is a 50-yard Jordyn's Adaptive Dash where children with disabilities will show off their speed using adaptive equipment to walk, roll or ride to the finish line. This special event is a huge hit with spectators and participants alike.

  We know you love your pooch and we're sure we would as well, but only service dogs with proper documentation are allowed inside the stadium at NAAC. For this reason, we ask that you leave your four-legged friends at home.

  Packet pick-up is available on Saturday, May 16 from 3:00-5:00 at Barquentine Brewing Company at Edgewater Public Market. You may also pick up your packet on race morning from 7:45 a.m. to 8:45 a.m. at NAAC.
