Diamond Triathlon & Swims

2012 was a big year for the UK, with the biggest sporting event in the world descending on London and a Diamond Jubilee to celebrate, it was party time on the streets of Great Britain. To commemorate, Human Race and British Olympic legend Daley Thompson launched a brand new multisport event designed to get everyone involved in the UK’s fastest growing mass participation sport – and now in its fourth year and with multiple distances on offer, there really is something for everyone!
