Walk 100km at Trailwalker
A friend has invited you to do this with them.
Teams of four trek or run 100km non-stop along the South Downs Way, aiming to finish in under 30 hours with a support crew meeting them along the route. The Gurkha Welfare Trust, a charity, organises Trailwalker and says the event originated as a Gurkha training exercise, with military teams taking part alongside civilians.

Plan this
Pick a day, or a month, and we will set out how to get ready, step by step, with a date and a reason for each. Events have fixed dates and entry or ticket deadlines. Physical events add a training plan from our guidance engine, and its length is set by the engine, not by the date you would like.
