Following much of the world-famous London Marathon route in reverse, The Vitality Big Half is a community running festival for everyone, no matter your age, background or running ability.

Starting at Tower Bridge, you’ll follow in the footsteps of the world’s best runners, taking in some spectacular views as you cross the river and finishing by the Cutty Sark.
