The most gruelling endurance "walk" you'll ever want to do unless you're mad. A major annual event run by the Gurkhas and Oxfam, with over £800,000 sponsorship raised being split between Gurhka charities and Oxfam. Teams of 4 compete to finish a 100km course; the lead Gurkha team usually finishes in less than 10 hours.

Jason along with three friends took part in this team event, but as only three of them finished, they were unplaced after 14 hours of effort. He was also out running the Tuesday after.
