The men's field for the 2026 TCS London Marathon on April 26 reads like a who's who of distance running royalty. Defending champion Sabastian Sawe, who won last year's race in a blistering 2:02:27 — the second-fastest time in London Marathon history — returns to face a cast of challengers that includes two Olympic champions and a half marathon world record holder.
Joshua Cheptegei, the Ugandan who holds world records at 5,000m and 10,000m and won Olympic gold in Paris across both distances, makes his London Marathon debut. The two-time Olympic champion's transition to the roads has been one of the most anticipated storylines in distance running, and London provides the flat, fast platform that could produce a sensational debut. His training partner and countryman Jacob Kiplimo, the half marathon world record holder at 56:42, finished second to Sawe last year and returns with the experience of the course and the hunger to go one better.
Sawe himself has predicted that it would take a course record for him to win back-to-back titles, given the quality of the opposition. The current London course record of 2:01:25 was set by the late Kelvin Kiptum in 2023, and while that mark remains one of the fastest marathons ever run, the convergence of talent in 2026 creates a realistic scenario in which it could be challenged. Ethiopian Yomif Kejelcha, the second-fastest half marathoner in history, is also making his marathon debut in London, adding yet another unknown quantity with world-class potential.
British interest centres on Emile Cairess, who is targeting Sir Mo Farah's British marathon record. Cairess has been on a steep upward trajectory since his breakthrough marathon performances in 2024, and the home crowd at London could provide the extra motivation to run the fastest time ever by a British athlete. With ideal conditions, the 2026 London Marathon men's race has the ingredients to produce one of the greatest road races in history.
