Sunday’s 2025 London Marathon smashed the Guinness World Record title for the largest number of finishers in a marathon, beating the previous record of 55,646 set by the TCS New York City marathon in November 2024.
56,640 runners crossed the iconic Buckingham Palace finish line on 27th April, making London Marathon a record-breaking event yet again. It’s already the most popular marathon in the world, with an astonishing 840,318 entries to the ballot this year, and the world’s largest annual one-day fundraising event with more than £1.3 billion raised for charity since 1981.
Mark McKinley, Director of Central Records Services at Guinness World Records said: “It’s amazing to see the growth of the TCS London Marathon over the last 45 events and this record marks the 18th consecutive year of our partnership, a collaboration that continues to offer runners the opportunity to add an extra challenge to their training. Congratulations to all the runners that took part, you are Officially Amazing!”
The high temperatures of 22°C made it one of London’s hottest marathons on record, but that didn’t stop the record number of runners from finishing – and setting some records of their own.
