Jacob Kiplimo Breaks Half-Marathon World Record with Historic Sub-57 Minute Run

The Ugandan runner shattered the previous record by 48 seconds in Barcelona, achieving the largest improvement in the event's history.

Jacob Kiplimo became the first person to complete a half-marathon in under 57 minutes, clocking 56:42 in Barcelona.
His performance broke the previous record of 57:30, set by Ethiopia's Yomif Kejelcha in October 2024, by an unprecedented 48 seconds.
Kiplimo credited ideal conditions, including 13°C weather and no wind, as factors in his record-breaking run.
The 24-year-old two-time world cross-country champion also set a 15km world best of 39:47 during the race.
Kiplimo announced his next race will be his marathon debut at the London Marathon on April 27, where he aims to continue his historic streak.
