London Marathon is making history once again. On 24 April the one millionth finisher crosses the world famous Finish Line on The Mall. The London Marathon organisers are celebrating this milestone in style - by creating the #oneinamillion campaign. The campaign will celebrate every runner who has completed 42.2k since the first race took place in 1981. London Marathon is the largest annual fundraising event on the planet where runners raised over £700 million for good causes since 1981. So far this year alone an impressive £16,280,074 was raised by Virgin Money London Marathon runners.
