Kenya's John Correa broke the course record with a time of two hours, one minute, and 52 seconds.

That's over a minute better than the previous record.

And at first, he wasn't aware he'd made history.

That's when I started to be happy.

Each of the top three finishers on the men's side ran times that were better than the previous high mark.

Correa repeated as champion, as did Sharon Locchetti, who set the women's division course record last year.

Marcel Hoog picked up his ninth victory in the men's wheelchair division, and Eden Rainbow Cooper won the women's wheelchair race for the second time.
