Ignoring warnings from race organizers, hundreds of runners took off along the Twin Cities Marathon and 10-mile race routes on Sunday after organizers canceled the events because of the hot weather forecast.
"We were already wheels on motion to get to the start when the 5:30 email came in," said Catherine Bunkers of Woodbury, who had been set to run the 10-mile race. "We threw our bibs on anyway."
"We just said, 'Well, let's see how far we can go in the heat,'" Leia Ward of Medina said.
Runners mixed with Sunday morning dog walkers along the river in downtown Minneapolis on what would have been the racecourse.
Marathoner Wolfgang Schauss of Detroit opted for a training run along the river Sunday morning, instead of trying to run 26.2 miles unsupported.
He remembered a steamy marathon in Richmond, Va., last year where runners dropped out all along the course — and the race did not seem to have enough medical staff and volunteers to help everyone.
He wondered if the Twin Cities Marathon's start time could have been made a little earlier, but said he understood the decision.
"Better safe than sorry," Schauss said. "Especially when you're an endurance runner, you don't always judge your limits."
