But when she was about 20 meters from the finish line, her legs started giving out.

That's when 17-year-old Ariana Luterman saw what was happening and jumped into action.

"I picked her up, and I tried as hard as I could to carry her over to the finish line but she did it all by herself at the end. " said Luterman. "That grit and determination it takes to get there, it was pretty amazing."

She is the first woman to run an unofficial time of 2 hours, 53 minutes and 58 seconds.

She was treated after the race and is recovering.
