A collection of the world’s best distance runners in the 5000m at the Prefontaine Classic will provide a preview of the IAAF World Championships London 2017 final when they take to the start line at the IAAF Diamond League meeting in Eugene on 27 May.

The question of the men’s 5000m comes in two parts. First, has the combination of another year of age, the 10,000m final he will already have run, and the accumulating weight of his medals slowed Mo Farah’s closing burst at all? Second, will any of his aspiring rivals work together to beat him, or has one of them developed the speed and savvy needed to do it alone?

Vivian Cheruiyot, the IAAF World Championships Beijing 10,000m champion, will chase a long distance double at the Rio 2016 Olympic Games after winning both over 25 laps of the track and then the 5000m at the Kenyan Olympic Trials in Eldoret on Thursday and Friday (30-1).

The Bauhaus-Galan is taking advantage of the recent rescheduling of the Kenyan Olympic Trials and will now welcome four of the East African nation’s world champions to the IAAF Diamond League meeting in Stockholm on 16 June.

Ethiopia’s Yomif Kejelcha will return to the IAAF Diamond League meeting in Eugene on 28 May after last year becoming the youngest ever winner of the 5000m at the Prefontaine Classic, organisers of the meeting announced on Monday (18).

Defending 3000m champion Caleb Ndiku leads Kenya’s team for the IAAF World Indoor Championships Portland 2016 on 17-20 March.

Kenya’s reigning world indoor 3000m champion Caleb Nidiku will take on his Ethiopian rivals Yenew Alamirew and Yomif Kejelcha over 15 laps of the track at the Indoor Meeting – Karlsruhe on Saturday 6 February, organisers for the opening 2016 IAAF World Indoor Tour event announced on Saturday (30).

Once again the question has to be posed, just how do you beat Mo Farah?

Double Olympic, world and European 5000m and 10,000m champion Mo Farah will drop down in distance and contest the 3000m at the Doha 2015 meeting, the opening competition of this year’s IAAF Diamond League on Friday 15 May, organisers announced on Tuesday (31).

Statisticians Mirko Jalava and A Lennart Julin look back at the best long-distance running performances of the year.

They won the first and last events of the weekend, but in between those victories hosts Africa could not hold off the might of the two strongest teams in the IAAF Continental Cup as Europe lifted the team trophy at the end of two days of competition in Marrakech.

After some outstanding men’s javelin throwing in the same stadium barely two weeks ago, there was another fine display in the IAAF Diamond League final. But instead of it being European champion Antti Ruuskanen who took the honours, it was Germany’s Thomas Rohler's turn to shine instead on Thursday (28).
