Mo Farah laid down a potent Olympic marker as he produced his third fastest ever 10,000m, 26min 53.71sec, to earn victory on the first of the two days of programmes at the International Association of Athletics Federations’ (IAAF) Diamond League meeting in Eugene.

Britain’s 33-year-old world and Olympic 5000 and 10,000m champion concluded the Prefontaine Classic’s traditional “distance night” with a dominant display on a Hayward Field track that brings out the best in him.

His two fastest times were also set in victories at Eugene - a personal best of 26:46.57 in 2011, and 26:50.97 last year.

Farah still doesn’t have the track record at Hayward Field however - that stands to his training partner Galen Rupp, who recorded 26:44.36 in 2014.

Against a field which included the Ethiopian who inflicted his last major track defeat, 2011 world 10,000m champion Ibraham Jeilan, Farah required all his tactical nous and finishing power to finish in front after taking the lead two laps out, being chased home by Kenya’s William Sitonik, who clocked 26:54.66, and Tamirat Tola of Ethiopia (26:57.33).

It was the Briton’s first track race since retaining his world titles in Beijing last summer.

Jeilan was the fifth man to finish under 27 minutes in this top quality race, clocking 26:58.75.

An opening effort of 6.92m was enough to earn home long jumper Brittney Reese maximum points in the first of three field events on the night counting towards the Diamond League rankings.

That kept the London 2012 gold medallist and triple world champion ahead of Serbia’s Ivana Spanovic, who managed 6.88, and Britain’s Lorraine Ugen, third with 6.76 ahead of Nigeria’s double Commonwealth champion Blessing Okagbare-Ighoteguonor, who had a best of 6.73.

Croatia’s Olympic discus champion Sandra Perkovic maintained her dominant start to the season as she earned another Diamond Race maximum with a best of 68.57, with Germany’s Nadine Muller second thanks to a final round throw of 65.31.

Home shot putter Joe Kovacs, who defeated Germanys David Storl in a titanic struggle at last year’s World Championships in Beijing, produced another pulverising display to win with 22.13 ahead of New Zealand’s Tom Walsh, whose best was 20.84.

Kovacs’s effort replaced his own mark of 21.47 at the head of this year’s rankings, and fell just 43cm short of his 2015 personal best.

Kenya dominated the women’s 5000m as expected, but the winner was not widely forecast - Hellen Obiri came home in 14min 32.02 to head Viola Kibiwot, who clocked 14:29.50, the second fastest time so far this year, in following Almaz Ayana home at the Rabat Diamond League meeting last Sunday as the Ethiopian recorded 14:16.31, the fifth best of all time.

Kibiwot was second in 14:35.13, just ahead of London 2012 silver medallist and 2015 world champion over 10,000m, Vivian Cheruyiot, who recorded 14:35.69, and Mercy Cherono, fourth in 14:37.08.
