Challenge-X is a 100km two-day event consisting of three stages. A grueling 20km trail run followed by a punishing 65km technical mountain bike stage over the rough terrain of the breathtaking Dartmoor National Park on Saturday 10th August, then a demanding 15km circuit of the Royal Marines Commando Endurance Course at Woodbury Common, Devon on Sunday 11th August. Athletes will camp overnight on Dartmoor between stages.
