This July we're taking part in Trailwalker UK, a 100km (60 mile) hike for teams of four from Petersfield in Hampshire to Brighton Race Course in Sussex, following part of the South Downs Way.

Walking at around 3mph it would take 24 hours, so allowing time for eating and blister bursting there'll be no time for sleeping!

But it's more than just walking though, the distance is equal to two and a half marathons, the ascent is equal to that of Ben Nevis, the highest mountain in the UK.

If that wasn't enough of a challenge - we're fund raising too!

All the money goes to support the work of Oxfam and the Gurkha Welfare Trust - we've pledged to raise £4000.

Over the coming weeks and months we'll be using this blog to introduce our teams, keep you updated with how our training walks, event-day preparation and fund raising!
