Gold Charities

Join us on the start line and take part in the London Triathlon for Great Ormond Street Hospital (GOSH). Every day, 618 children and young people from across the UK arrive. Every day, doctors and nurses battle the most complex illnesses, and the brightest minds come together to achieve pioneering medical breakthroughs. Join team GOSH and make a difference to the lives of these children. A better future for seriously ill children starts here.

By 2020, almost one in two of us will get cancer and it’s the toughest fight most of us will ever face. We want to reach and improve the lives of everyone living with cancer and we need your support. Join team Macmillan at the London Triathlon and help us raise vital funds to support our work.

Together we are all Macmillan.
