Biography
Jacob Kiplimo was born on 14 November 2000 in Kween District, Uganda. He is a long-distance runner who has established himself as one of the most decorated and versatile athletes in the history of the sport, holding world records and championship titles across multiple disciplines including cross country, road racing, and track events. His rise through the ranks of global athletics has been characterized by consistent excellence from a young age, making him a central figure in the ongoing tradition of East African distance running dominance.
Kiplimo announced himself on the world stage at the 2017 World Cross Country Championships, where he claimed the junior title. He subsequently built on that foundation by winning the senior cross country world title in 2023, 2024, and 2026, making him a four-time World Cross Country champion in total. These victories across different age categories and over multiple years underscored his ability to compete at the highest level throughout a sustained period rather than in a single breakthrough moment.
On the track, Kiplimo earned a bronze medal in the 10,000 metres at the 2020 Tokyo Olympics and followed that performance with another bronze in the same event at the 2022 World Athletics Championships in Eugene, Oregon. His personal bests of 12:40.96 in the 5000 metres and 26:33.84 in the 10,000 metres place him among the top ten performers of all time in both events, reflecting his exceptional speed over the shorter track distances as well as his endurance.
In road racing, Kiplimo has pushed the boundaries of human performance in the half marathon and marathon. At the 2025 Barcelona Half Marathon, he ran 56:42, surpassing the existing world record by 48 seconds. However, World Athletics declined to ratify the performance as an official world record due to the use of a lead pace car during the race. Kiplimo returned to the half marathon the following year at the 2026 Lisbon Half Marathon and clocked 57:20, again breaking the world record, though that time was also pending ratification. His officially recognized world record in the half marathon stands as a product of his continued pursuit of peak performance on the roads.
Kiplimo has also demonstrated formidable ability at the marathon distance. At the 2026 London Marathon, he ran 2:00:28, a time that ranks him as the third-fastest marathoner in history. This performance confirmed his status not merely as a track specialist or half marathon runner but as a complete long-distance athlete capable of competing for the highest honors across the full spectrum of distance events.
Before Fame
Jacob Kiplimo grew up in Kween District, a mountainous region in eastern Uganda near the border with Kenya. The area sits at high altitude and has historically produced elite distance runners, providing Kiplimo with both the geographical and cultural conditions conducive to developing endurance from a young age. Like many athletes from the region, he likely began running competitively during his school years, participating in local and national cross country events that serve as the primary development pathway for Ugandan distance runners.
Kiplimo came of age during a period when Ugandan athletics was gaining increasing international recognition, with athletes such as Stephen Kiprotich and Joshua Cheptegei establishing the country as a serious force in global distance running. Competing within this environment, and training in proximity to some of the world's best runners, Kiplimo developed rapidly. His selection for international junior competition reflected the strength of Uganda's talent identification system, and his junior world cross country title in 2017, achieved before he turned 17, signaled that he was not merely a promising prospect but an athlete already operating at world-class level.
