The London Marathon is an annual marathon event held in London, United Kingdom. Founded by athletes Chris Brasher and John Disley in 1981, it is typically held in April. 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. The race has several components: it has a mass race for the public, professional races for men and women long-distance runners, elite level wheelchair races for men and a women, plus a 3-mile mini marathon event for under-17 athletes. The mass race is the largest marathon event in the United Kingdom and its third largest running event (after the Great North Run and Great Manchester Run). There is a significant charity running aspect to the marathon, with participants helping to raise over £1 billion since its founding, including £66.4 million at the 2019 London Marathon which was the highest amount for a single-day fund-raising event.
