Paula Radcliffe wasn't able to make a winning comeback in the New York marathon, only finishing fourth.
Derartu Tulu from Ethiopia won the race, pulling away from Russia's Ludmila Petrova in the final stages.
Radcliffe was chasing her third New York marathon victory in a row, but couldn't cross the line first and looked like she had a sore leg too.
Radcliffe has had a tough time in recent months, suffering from tonsillitis and a foot operation.
It wasn't just Radcliffe making a comeback though - Tulu hadn't won a major marathon since 2001 in London.
