The London Marathon is an annual marathon held in London, United Kingdom, and is the 2nd largest annual road race in the UK, after the Great North Run in Newcastle. Founded by athletes Chris Brasher and John Disley in 1981, it is typically held in April but has moved to October for 2020 and 2021 due to the COVID-19 pandemic. The 2022 edition was also postponed to October with Hugh Brasher stating "We believe that by moving the 2022 event to October we give ourselves the best chances of welcoming the world to the streets of London, enabling tens of millions to be raised for good causes and giving people the certainty that their hard work and training will allow them to experience the amazing crowds cheering them every step of the way from Greenwich to Westminster". The largely flat course is set around the River Thames, starting in Blackheath and finishing at The Mall. Hugh Brasher (son of Chris) is the current Race Director and Nick Bitel its Chief Executive.
