The London Marathon is contemplating a significant change for the 2027 elite women’s race, potentially allowing male runners and pacemakers to compete alongside female athletes to enhance the chances of achieving faster times and breaking world records.

Currently, the overall world record in mixed races is held by Ruth Chepng’etich at 2:09:56, a mark set during the 2024 Chicago Marathon. However, the record has been marred by controversy, as Chepng’etich received a three-year ban for a doping violation shortly after the event.

Tigst Assefa, who set the women-only race world record at 2:15:41 during the 2026 London Marathon, was on track to break the overall record at the recent Berlin Marathon but suffered a devastating Achilles tendon rupture, finishing in 2:11:04.

Hugh Brasher, CEO of the London Marathon, expressed his heartbreak over Assefa's injury and openness to changes that might allow female athletes, including Assefa should she recover, to challenge Chepng’etich’s controversial record next year. He emphasized the importance of having a women’s-only record in the future while acknowledging that mixed races have historically produced remarkable performances, citing Paula Radcliffe's mixed race record of 2:15:25 from 2003.

Brasher mentioned that discussions are ongoing with top female runners regarding their preferences for the race format. He noted, “We talk to the women and what they want to achieve, those conversations are still going on about 2027.” He also highlighted the competitive nature of the London Marathon, asserting that it is often seen as tougher to win than the Olympics or World Championships. The final decision regarding the elite fields is expected in January, with Brasher assuring fans that the upcoming races will be thrilling and competitive.
