2027 TCS London Marathon
With over 56,000 runners and more than one million spectators lining the streets of London, the TCS London Marathon on 25 April 2027 is one of the most iconic races in the world, and an experience like no other.
It’s a serious challenge, but one that brings an incredible sense of achievement. With team Sebastian’s Action Trust behind you, every mile you run will make a real difference to families facing life-limiting childhood illness.
