The 2026 Leadville Trail 100 mountain bike race proceeded in Colorado with a modified course after wildfires damaged the traditional route [1].
The adjustment represents a significant shift for one of the most storied events in mountain biking. By altering the course, organizers avoided hazardous terrain while attempting to maintain the competitive integrity of the race despite environmental losses.
Life Time, the event organizer, removed the iconic Powerline climb from the course [4]. This decision followed the Willow Fire, which burned 7,500 acres [5] near Leadville. The fire's impact forced a reroute to ensure the safety of the participants and staff.
"The wildfire forced us to reroute the Powerline climb, but the spirit of the race remains unchanged," a Life Time spokesperson said [6].
Melisa Rollins, a competitor aiming for her second victory, expressed the emotional toll of the landscape's destruction. "Iconic Powerline not being part of the race is devastating but it's even more devastating that the mountain is on fire," Rollins said [2].
Race officials said they worked with local authorities to adjust the course while prioritizing rider safety [3]. While the Powerline climb is missing, the 2026 route continues to closely follow the traditional path [4].
The event remains a cornerstone of the U.S. mountain biking calendar. Organizers said that the decision to move forward with a modified route was necessary to preserve the legacy of the race while acknowledging the reality of the region's wildfire impact [1].
“"Iconic Powerline not being part of the race is devastating but it's even more devastating that the mountain is on fire."”
The modification of the Leadville Trail 100 highlights the increasing vulnerability of outdoor sporting events to climate-driven disasters. As wildfires continue to impact high-altitude regions in the U.S., organizers must balance the preservation of athletic tradition with the immediate safety risks of burn scars and unstable terrain.
