People for the Ethical Treatment of Animals (Peta) has joined forces with world champion free runner Tim "Livewire" Shieff to push the benefits of living life as a vegan.
A video by the organisation shows Shieff jumping and somersaulting his away across London before doing a handstand on top of a building.
The video ends with the strapline "Do More Than Survive. Thrive. Choose Vegan".
Shieff himself has been vegan for the past two years and appears in another YouTube video for Peta speaking about the benefits of the diet.
