Fell runner John Fleetwood is about to embark on his biggest challenge yet - a journey along the full length of the Alps from Slovenia to Monaco. On this epic of around 1850km he aims to stick to the high ground as much as possible, including via ferrata and some major peaks
John - Have you looked into what Nicolas Crane did quite a while back? A longer route and no doubt lower down but pretty epic at 18months long and unsupported. Its a good read.
