Kenya’s Jacob Krop moved to sixth on the world all-time list with his winning 12:45.71 run in Brussels to book his place in the final and will look to build on that when he goes up against some strong opposition in Zurich.
The 21-year-old world silver medallist recorded the fastest time in the world so far this year to beat USA’s Grant Fisher and his Kenyan compatriot Nicholas Kipkorir, who will both also be on the start line on Wednesday.
Fisher’s performance of 12:46.96 was a North American record that moved him to 12th on the world all-time list.
Ethiopia’s Berihu Aregawi won last year’s title on the city centre course and a few months later he further proved his road race strength, setting a world 5km record of 12:49 in Barcelona at the end of the year.
His Diamond League campaign this season has included a win in Eugene in May was well as a runner-up finish over 3000m in Monaco, where victory was claimed by Burundi’s Thierry Ndikumwenayo in a world-leading PB and Diamond League record of 7:25.93.
