Ugandan Joshua Cheptegei broke a 16-year-old world record in the 5000m by nearly two seconds, clocking 12:35.36 in Monaco on Friday.
Cheptegei, the 2019 World champion, took 1.99 seconds off Ethiopian legend Kenenisa Bekele‘s world record from 2004. Bekele is also the 10,000m world-record holder and the second-fastest marathoner in history.
“It took a lot of mind setting to keep being motivated this year because so many people are staying at home, but you have to stay motivated,” Cheptegei said, according to organizers. “I pushed myself, I had the right staff with me, the right coach.”
