Colorado fires forcing race directors to rethink summer events

July 9, 2026

Colorado wildfires and related public-land closures have forced several summer endurance events to be canceled or rerouted, including the cancellations of the Ouray 100 and the Silver Rush races, while other high-profile races like the Hardrock 100 remain scheduled for now. Organizers say closures, smoke and safety concerns — plus drought-driven fire risk and poor air quality — are forcing race directors to rethink routes, timing and contingency plans for Western events this season.
