The 2026 London Marathon will feature the deepest British women's field in the race's history, with five of the nation's 10 fastest female marathon runners all set to compete on April 26. Charlotte Purdue, Rose Harvey, Abbie Donnelly, Eilish McColgan, and Jessica Warner-Judd will battle for British honours in a race that could redefine perceptions of British women's marathon running.
Purdue enters as the fastest Briton in the field, with her personal best of 2:23:26 set at the 2022 London Marathon placing her third on the British all-time list behind Paula Radcliffe and Mara Yamauchi. The 30-year-old has been consistent at the highest level for several years but has yet to produce the breakthrough performance that her talent deserves at a home marathon.
Rose Harvey represents perhaps the most exciting proposition. After a remarkable 2025 season that saw her improve her personal best twice, Harvey has been training at altitude in Kenya and producing encouraging workout times that suggest she could challenge for sub-2:22 if the conditions are favourable. Her aggressive front-running style could see her involved in the early stages of the elite race.
Eilish McColgan's marathon journey has been one of the most closely watched in British athletics. The daughter of Olympic medallist Liz McColgan, she finally cracked the marathon puzzle in 2024 after several frustrating early attempts, and her improving trajectory suggests London could produce another step forward. McColgan's 10K and half marathon pedigree gives her the speed foundation to compete at the highest level.
The unprecedented depth of British women in the London field reflects a broader trend in UK distance running. Where once British women struggled to break 2:30, there is now a generation capable of running 2:22-2:25 — a standard that would have been unthinkable a decade ago. The race within the race for British honours promises to be almost as compelling as the battle for the podium between the world's best.
