Uganda's Jacob Kiplimo reclaimed the men's half marathon world record on Sunday winning in Lisbon in 57 minutes and 20 seconds, to take 10 seconds off the time set in 2024 by Yomif Kejelcha.

Kiplimo had previously set the record in Lisbon in 2021 before Ethiopian Kejelcha shaved off one second in Valencia.

In a race without pacemakers, Kiplimo covered the first five kilometres in a rapid 13:28 with Kenyans Nicholas Kipkorir and Gilbert Kiprotich on his heels.

After the trio reached 10km in 27:00 Kiprotich faded.

Previous world record attempt

When the pace dropped as the leaders passed 15km in 40:52, Kiplimo, who had an eye on the record, accelerated and ran the next 5km in 13:31, a pace he kept up to the end.

"After the first 10km, I thought the world record was possible. I tried to keep pushing the pace in the final two kilometres," he said at the finish.

Kipkorir crossed the line 48sec behind with Kiprotich a distant third.

Kiplimo ran 56:42 in Barcelona last year, but World Athletics refused to ratify the record because, it said on Sunday, "the race conditions were not fully compliant with World Athletics rules".

Ethiopian Tsige Gebreselama retained the women's title in 1:04:48.
