Runners say a new turnaround at mile 24 was not marked. Runners went down the riverwalk behind the Fisher Cats ballpark, then turned around and doubled back.

But the top two runners missed the turnaround and got lost with just 2.2 miles left in the race and never finished.

Race director Jane Cornell says she placed a big sign at the turnaround before the race. Organizers are still trying to figure out exactly what happened. Cornell says the sign could have blown over in the high winds.

The error cost the lead runner, Jason Ayr of Westfield, Massachusetts, a potential $1,500 in first-place prize money. He says he never saw the sign or a volunteer telling him to turn around.

Eventually, he hit a Manchester neighborhood and a dead end.

"My heart dropped because it was super frustrating. Obviously I really thought that I was going to win it and it was really frustrating to realize that wasn't the case anymore," Ayr says.
