London is preparing to host the 2026 TCS London Marathon on Sunday, with approximately 59,000 runners expected to begin the race from Blackheath. The Met Office forecasts dry and pleasant spring weather, with warm temperatures reaching up to 19C in the capital.
These conditions are near ideal for the marathon, especially ahead of anticipated rain and thunderstorms predicted to arrive on Monday across southern England and the Midlands.
Sunshine Boost For Runners
The marathon day will be mostly dry and bright, starting cool in the morning with mild temperatures rising throughout the day. Runners are advised to prepare for a cool wait on the start line at Greenwich Park and Blackheath, where highs are forecast between 17C and 19C.
The Met Office highlights light winds and a low risk of rain, creating favourable running conditions on the largely shadeless city course.
UV And Pollen Warnings
Despite the comfortable temperatures, runners should be aware of high UV levels and a significant oak pollen count across southern England, particularly in London. Allergy sufferers are advised to take precautions such as using antihistamines and keeping windows shut overnight to minimise symptoms.
Notable Competitors Set To Appear
The race features a strong field, including Sir Mo Farah’s return to the event alongside rugby star Ellie Kildunne. Celebrity runners like Jack O’Connell, James Norton, and Harry Judd add to the appeal.
In the men’s wheelchair race, Marcel Hug aims to equal David Weir’s record, while Catherine Debrunner seeks to challenge the women’s wheelchair times.
