A total of 167,687 non-UK residents applied for the international ballot.
More than 53,000 people have completed the 26.2-mile journey across the capital this year, with 44 Guinness World Records broken and £67 million raised so far for charity.
-Hugh Brasher, TCS London Marathon Event Director, said: “This is an absolutely phenomenal total. Furthermore, the increase in female candidates, going from around 43% last year to 49% this year, is exceptional and brings us closer for the first time to parity between male and female candidates.
“Marathon Day is always an extraordinary and inspiring day where we celebrate the best of humanity.
“The unique camaraderie of the event and incredible support from the huge crowds shows London at its best and this year, in a world plagued by many challenges, we felt like we were living through those magical days of London 2012, where joy and love were everywhere.”
The 2025 TCS London Marathon will take place on April 27.
