The Lloyds TSB Cardiff Half Marathon has grown into one of the largest road races in the United Kingdom. The first event took place back in 2003 and the 10th Anniversary was celebrated in 2012. The event is not only the U.K’s second largest half marathon; it is Wales’ largest road race and Wales’ largest multi-charity fundraising event. The race is sponsored by Lloyds TSB and supported by strategic partners, Cardiff Council, Welsh Government, Vale of Glamorgan Council and Welsh Athletics. The 2012 event witnessed the introduction of a new course which encompassed Cardiff’s most iconic landmarks and was enthusastically recieved by runners. The size of the field has dramatically expanded during the race’s history; from just under 1,500 runners in 2003 to 18,000 in 2012.
