All-Out Beat the Heat 2027

All-Out Beat the Heat takes place in Westminster, Colorado, on the Big Dry Creek Trail near Standley Lake, offering 5K, 10K, and half marathon distances. This is the 15th year for the event, organized by All-Out Multicourse. It also functions as an official BOLDERBoulder qualifier, allowing runners aiming for a seeded start to achieve a qualifying time here. Each distance follows Big Dry Creek Trail southwest. The course is described by the organizer as having moderate terrain, neither excessively hilly nor completely flat. Half marathon participants experience the longest course, with sights of Standley Lake, the Front Range, and the Flatirons in the distance. The race benefits Adaptive Adventures, provides virtual 10K and half marathon options, and is part of All-Out’s Endless Series, alongside Fallfest.
