Long-distance runner Galen Rupp has broken the American national record for the 10,000m on day one of the Prefontaine Classic in Eugene.
Rupp, who took the silver behind Mo Farah in the event at London 2012, beat his old record by nearly four seconds to run a time of 26:44.36.
The 28-year-old had gone into the race, on what is known as 'Distance Night in Eugene', expecting a fast time, but was clearly surprised to have bettered his 26:48.00 from 2011.
It was a flying last lap of 58.5s which won Rupp the race, stretching clear of runner up Paul Tanui, a bronze medallist from last year's World Championships in Moscow, by five seconds.
Tanui did still manage a personal best time, though, as did the rest of the top four - Bedan Koroki (26:52.36) and Stephen Sambu (26:54.61).
It was Rupp who stole the show, though. The US athlete is the teammate of Farah, and on this showing could compete with the Brit.
But he wasn't the only one to impress on the night. World and Olympic champion Sandra Perkovic extended her winning run by winning the discus event with a meeting record of 69.32m, while Ivana Spanovic triumphed in the long jump with a Serbian national record of 6.88m.
