Kenya's Brigid Kosgei won the Chicago Marathon on Sunday with a time of 2 hours 14 minutes 4 seconds, breaking the previous world record by 81 seconds.

At 25, the Kenyan defended her title after winning last year's event, and put almost 7 minutes between herself and her competition. Both from Ethopia, Ababel Yeshaneh finished second with a time of 2:20:51 and Gelete Burka came in third at 2:20:55.

The previous world record time of 2:15:25 was set by Britain's Paula Radcliffe in 2003 at the London Marathon.

Simone Biles is the greatest gymnast of our time – or any time in history. She proved that Sunday at the World Championships, where she raked in her 24th and 25th world medals, both gold.

Biles, 22, took home five of the six golds to be won in Stuttgart, Germany, winning the top of the podium in team competition, all-around, and vault in addition to floor and beam. (On the uneven bars, she took fifth.)
