Henry, Oli, Gilbert and Tim are taking on the Oxfam Trailwalker https://oxfamapps.org.uk/trailwalker. 

It is the ultimate team endurance event with the challenge to walk, jog or run (we will be walking) 100km non-stop across the South Downs Way in under 30 hours in a team of four. 

The event takes place in order to raise funds to support the work of both The Gurkha Welfare Trust www.gwt.org.uk and Oxfam Great Britain.
