Hardrock 100 organizers said Thursday morning the race will go ahead as planned, clearing the 100-mile ultramarathon to start Saturday in Silverton despite smoke from nearby wildfire activity. The late call came less than 48 hours before about 150 runners were due to line up for one of Colorado’s hardest endurance tests.
The race is no small thing to green-light. It stretches 100 miles, climbs more than 33,000 feet over 13 mountain passes and sends runners through Telluride, Ouray and the ghost town of Sherman, all within a 48-hour cutoff. Organizers also had to weigh the decision against the Gold Mountain Fire, which was burning north of Ouray and east of Highway 550 and had grown to more than 32,000 acres while remaining 8% contained on Thursday morning.
Dale Garland said the decision was not made in isolation. On Wednesday, he said the process involved talking first with stakeholders, and he added that nine separate agencies were part of the discussion. Hardrock also works through permits from three towns, four counties, the U.S. Forest Service and the Bureau of Land Management, which means a go-ahead has to clear more than one layer of authority before anyone can toe the line.
The final call rested on an air-quality matrix built from Environmental Protection Agency monitoring stations in Silverton, Ouray and Telluride. If all three readings were below 100 on the Air Quality Index Thursday morning, the race could proceed. If they landed between 101 and 149, the race could still continue, with runners allowed to defer until next year. Any reading above 150 would have forced a cancellation.
That framework helps explain why Hardrock moved ahead when other endurance events did not. The Ouray 100 was canceled nearly two weeks before the race, and Leadville’s Silver Rush mountain bike and ultramarathons were also called off. August’s Leadville Trail 100 remained unresolved, underscoring how quickly wildfire smoke and fire behavior have changed the outlook for racing in southwestern Colorado this summer.
Ouray 100 organizers said the Gold Mountain Fire had already burned sections of their course and that smoke added health risk in a race where respiratory issues are already among the most common medical problems. They said the cancellation reflected an accumulation of risk, including uncertainty over trail access, emergency response, worsening fire weather and the possibility that generators or camp stoves at aid stations could add ignition risk. Hardrock, by contrast, chose to proceed with those same conditions hanging over the region.
For the runners and the crews already traveling to Silverton, Thursday’s announcement removed the biggest question left on the calendar. The next one is narrower and harder: whether the smoke holds steady enough for the race to begin on Saturday the way organizers expect, or whether changing fire conditions force the course to become a moving target once the field is already in motion.
