The 2025 TCS London Marathon has officially smashed the global record for most marathon finishers. Guinness World Records, which celebrates its 70th year in 2025, acknowledged the accomplishment, with 56,640 runners successfully finishing the race. This milestone breaks the previous record of 55,646 finishers set by the TCS New York City Marathon in November 2024.
In addition to the overall record, an amazing 41 Guinness World Records titles were broken throughout the marathon, with 87 official attempts. Angus Leckonby set the fastest marathon time for a male (II1) at 3:36:38, while Zoe Cowell-Jones ran the quickest marathon by a female mascot in 3:19:18.
