Following the finals on the last day, Andy Murray took part in a charity event called "Rally against Cancer" alongside former British no. 1 Tim Henman, in which they faced off against Murray's coach, former world no. 1 and 8-time Grand Slam champion Ivan Lendl, and world number 6 Tomas Berdych. The event was organised in order to raise money for the Royal Marsden Cancer Charity, after British Davis Cup player Ross Hutchins was diagnosed with Hodgkins Lymphoma at the end of 2012. Following the one set affair, in which the Brits emerged victorious, Murray and Henman then teamed up with a number of British celebrities, including comedians Jimmy Carr, Michael McIntyre and Jonathan Ross, actor Eddie Redmayne, businessman Sir Richard Branson and mayor of London Boris Johnson. The initial target for the event was £100,000, however this was exceeded by over £50,000 during the event. Furthermore, Murray donated his entire prize money pot of around £73,000 towards the charity.
