The race is based on a modified version of the Cape Wrath Trail, which runs from Fort William to Cape Wrath. The Cape is only accessible by foot or boat, and the route normally takes walkers around 20 days to complete.
The runners have to complete each stage within the cut-offs to be able to continue and each evening the runners arive at the camp to find tents, kit and kitchen awaiting them.
Though the race is just a few hours old, Thomas Adams and Marcus Scotney lead.
