Simon Richardson and James Lowsley-Williams are heading to Nepal to tackle the Annapurna Circuit; a 230 km trail that circumnavigates the mountain. Known as the best long distance hike in the world, an experienced hiker will take around 20 days to complete the route on foot; Si and James are attempting to ride it in just 5. Joined by local Nepalese mountain bike legend, Mangal Lama, they’ll battle extreme weather conditions, treacherous single track, and perilous high altitude as they try to complete the iconic Annapurna Circuit.
