A runner at the Sioux Falls Marathon this weekend stepped into some hot water after organizers said his record-setting finish time at the event was a bit too fast, and later determined that he had only run 13.1 miles instead of 26.2 miles.

According to the Sioux Falls Argus Leader, 37-year-old Olok Nykew, of St. Paul, Minn., crossed the marathon's finish line 25 minutes ahead of the existing record for the race. However, after further review, race officials said although Nykew had crossed the finish line first, he had only registered for and completed a half-marathon.

Nykew, originally of the Sudan, said he wasn't sure what happened with the mix up.

"Maybe I'm lost, I don't know," he told the newspaper after crossing the finish line. He said there must have been a mix up with his registration.

"It was an honest mistake," Nykew said.

Organizers disqualified Nykew from the race and a new winner was crowned when 29-year-old Justin Gillette, of Goshen, Ind., crossed the finish line with a time of two hours, 30 minutes and 10 seconds -- the fastest ever for the Sioux Falls event.
