Jacob Kiplimo

Jacob Kiplimo (born 14 November 2000) is a Ugandan long-distance runner and former world record holder in the half marathon. A four-time World Cross Country champion, Kiplimo won the junior race in 2017 and senior titles in 2023, 2024, and 2026. On the track, Kiplimo won bronze medals in the 10,000m at the 2020 Tokyo Olympics and the 2022 World Athletics Championships. His personal bests of 12:40.96 in the 5000m and 26:33.84 in the 10,000m rank within the top ten all-time in those events. Kiplimo is also the third-fastest marathoner of all time, having run 2:00:28 at the 2026 London Marathon. At the 2025 Barcelona Half Marathon, Kiplimo ran a time of 56:42, breaking the world record by 48 seconds. However, World Athletics did not ratify the performance as an official world record by due to assistance by a lead pace car. At the 2026 Lisbon Half Marathon, Kiplimo broke the world record again, clocking 57:20. That time has yet to be ratified.
