Mark, who’s about to retire from a career as a Civil Engineer, had considered swimming the channel or the Straits of Gibraltar and then realised there was an ideal opportunity on his doorstep, “I’ve swum in many beautiful spots around Cornwall and the Isles of Scilly and it suddenly occurred to me that we have a perfect challenge right here. I can’t do the swim in one go, so plan to tackle it piece by piece over the next two years. The distance is the swimming equivalent of 46 marathons, but I’ll swim between five and ten kilometres each time and can wait for suitable and safe conditions.”

Mark’s inspiration comes from the nursing teams who cared for his wife Gill’s father, Peter Saville. “He was a very brave man and was superbly cared for at Mount Edgcumbe Hospice. He received amazing support, which I was stunned to find is funded mostly by charitable donations. I hope we never need the team there again but our community most certainly will and I really think fundraising for them is worth all the effort.”

Mark has already started the 2017 season, taking his trusty camper van to the end point of each swim, then cycling back to the start, swimming and then driving to collect the bike. “It’s a great way to see Cornwall up close and personal” he says with a grin. “I‘ve also enlisted the support of local sea kayakers and friends and professionals with rigid inflatable boats (RIB’s) to support me, more especially for the exposed sections of coast around Land’s End and The Lizard. I’d be delighted to welcome any serious sea swimmers who’d like to join me on any of the legs too.”
