An epic 240+ mile race through Utah’s rugged canyon country turned into an overnight survival challenge after torrential rain, flash flooding and powerful winds stranded about 70 runners and volunteers, forcing organizers to pull the plug on the entire event.

The storm was linked to the remnants of Tropical Storm Rachel, which helped fuel heavy rain across parts of the Southwest.

The race's cancellation came as forecasters warned of worsening conditions.

Flash floods descend on course

The trouble began Saturday when dangerous weather hit parts of the Moab 240 course, making Cottonwood Creek too dangerous to cross. Floodwaters blocked the route, leaving runners unable to continue safely.

Runner Brock Painter described the conditions on social media, saying he and other runners were practically skiing down a mountain as heavy rain poured down and mud made footing difficult.

And the rain was only part of the problem.

Powerful winds threatened to blow away aid station structures, while falling trees and freezing temperatures added to the danger. Video from the race showed rain blowing sideways as runners battled the elements.

Rescuers help runners get out

Emergency responders were notified Saturday, and a helicopter surveyed the area early Sunday to help identify safe evacuation routes.

By Sunday morning, runners were escorted out of the stranded area.

Some were picked up by all-terrain vehicles before being transported to Moab by bus. San Juan County sheriff's deputies and other local responders also helped with rescues.

All runners were accounted for, and reports indicated no serious injuries.

Mother Nature makes the final call

Organizers officially canceled the race Sunday afternoon.

"Weather has other plans," Destination Trail said, explaining that runner safety had to come first.

For athletes who trained for months to tackle one of the country's most demanding endurance races, it was a disappointing finish.

But the ordeal was a powerful reminder that even the toughest athletes can't outrun Mother Nature.
