Ethiopian runner Yomif Kejelcha sets a new men’s half marathon world record at a World Athletics road race in Buenos Aires, running 56 minutes 51 seconds. Multiple outlets report the performance is 29 seconds faster than the previous mark held by Uganda’s Jacob Kiplimo.

The record had last been claimed by Kiplimo earlier in the year, with a 57:20 time in Lisbon in March. This latest result is described as Kejelcha reclaiming the top spot and also as the second occasion in roughly five months where the half marathon record has been broken. Both the BBC and sports coverage note the record times are pending official ratification by World Athletics, meaning the marks are not yet final.

Across the reports, the central points align on the location (Buenos Aires), the athlete (Yomif Kejelcha), the time (56:51), and the prior record-holder/time (Jacob Kiplimo’s 57:20 from Lisbon). The differences are mainly in wording, with some outlets emphasizing the size of the margin and others the recent back-and-forth nature of record attempts.
