The double Olympic and world champion runs his third-fastest ever 10,000m for victory as he opens his Olympic season in Eugene

Mo Farah started his Olympic season by clocking 26:53.71 to win the 10,000m at the Prefontaine Classic in Eugene.

That world-leading mark is the double Olympic, world and European champion’s third-fastest ever 10,000m behind his 2011 and 2015 Pre Classic winning times, with his 26:46.57 British record having been set at this event five years ago.

The 5km point had been passed in around 13:23, with Farah to the fore. The Briton was behind Kenya’s William Malel Sitonik on the final bend but surged past him in the home straight to continue his win streak over the distance. Farah’s last defeat over 25 laps of the track came in 2011 when he finished behind Ethiopia’s 2011 world champion Ibrahim Jeilan at the World Championships in Daegu.

The top five all went sub-27:00, with Farah followed by Sitonik with a 26:54.66 PB, Ethiopia’s Tamirat Tola with a 26:57.33 PB, Kenya’s Stephen Sambu with 26:58.25 and Jeilan with a 26:58.75 PB.

Eritrea’s half-marathon world record-holder Zersenay Tadese ran 27:00.66 for sixth.

The Eugene 10,000m was Farah’s first outdoor track race since last summer’s IAAF World Championships in Beijing, where he retained his 5000m and 10,000m titles. So far in 2016 he has also finished second at January’s Great Edinburgh XCountry, won the Glasgow Grand Prix 3000m in February and bagged bronze at the IAAF World Half Marathon Championships in Cardiff in March.

The men’s 10,000m was the final event of ‘Distance Night in Eugene’, with Prefontaine Classic action to continue at 12:15 (20:15 BST) on Saturday (May 28).

The women’s 5000m, missing world 1500m record-holder Genzebe Dibaba through injury, was won by Kenya’s Hellen Obiri in 14:32.02 from Viola Kibiwot with 14:35.13 and world 10,000m champion Vivian Cheruiyot with 14:35.69. USA’s Molly Huddle was 11th in 14:48.14.

Three Diamond League events also took place. USA’s Olympic champion Brittney Reese won the long jump after a first-round leap of 6.92m from Serbia’s Ivana Spanovic (6.88m) and Britain’s Lorraine Ugen (6.76m), while Croatia’s Olympic champion Sandra Perkovic won the discus with a throw of 68.57m. Britain’s Jade Lally, who threw an English discus record of 65.10m earlier this year, placed seventh in Eugene with 61.83m.

USA’s world champion Joe Kovacs won the shot put with a world-leading 22.13m from New Zealand’s Tom Walsh with 20.84m.

Poland’s world champion Pawel Fajdek won the non-Diamond League hammer competition with a throw of 80.28m, with Britain’s Nick Miller placing sixth with 74.89m. The ‘USATF High Performance’ 800m was won by Alysia Montano in 2:00.78.
