Sebastian Sawe of Kenya clinched a significant victory at the London Marathon by making a decisive breakaway with around 10 kilometers remaining, finishing with a time of 2 hours, 2 minutes, and 27 seconds. Sawe's strategic move during a drinks station, where he opted not to take water, allowed him to pull ahead of his competitors, ultimately establishing a gap his closest challenger, Jacob Kiplimo, could not close. Kiplimo, a debutant in full marathons and the half marathon world record holder, finished second, trailing Sawe by approximately 70 seconds. Sawe's triumph marks his second marathon win, following his victory in Valencia in 2024, and continues Kenya's winning streak in the men's London Marathon. In the women's race, Tigst Assefa of Ethiopia emerged victorious by overtaking Joyciline Jepkosgei towards the race's conclusion, earning her first London Marathon title.

Sebastian Sawe decisively won the London Marathon, marking the most significant victory of his career, after breaking away from a leading pack with about 10 kilometers left in the race.

During a critical moment at a drinks station, Sawe chose not to hydrate, which allowed him to accelerate ahead of his competitors, despite warm weather conditions, ultimately leading to his solo finish.

Jacob Kiplimo, making his debut in a full marathon and known for his half marathon world record, was the only runner capable of challenging Sawe, but could not close the gap, finishing in second place about 70 seconds behind.

Sawe's victory in London is his second marathon win, his first being in Valencia in 2024, and he becomes the fourth consecutive Kenyan to win the men's race in London.

In the women's race, Tigst Assefa of Ethiopia achieved her first London Marathon victory by overtaking Joyciline Jepkosgei near the end, showcasing her competitive edge and endurance.
