The London Marathon is a marathon race that has been held each year in London since 1981, usually in April. While it is run over the traditional distance, it is not the conventional marathon it was intended to be; it has become a large, celebratory sporting festival. It is the second largest marathon in the world in terms of participants.
According to the race organisers, it is now the largest annual fund raising event in the world with the 2006 participants raising over £41.5million for charity, bringing the total amount raised for charity by runners since the race began back in 1981, to a grand total of £315 million.
