Jacob Kiplimo took back the world record in the half marathon with 57:20 in Lisbon

World Athletics said in a press release that the world record time is provisional.

The time of 57 minutes, 20 seconds is a ten-second improvement on Ethiopian Yomif Kejelcha's world record from 2024.

Kiplimo ran a half marathon in Barcelona a year ago in 56 minutes, 42 seconds, but earlier in February this year it was announced that the time had been invalidated. This was because the Ugandan had run too close to the lead car, reducing air resistance. He also reportedly received instructions from his coach during the race.
