Roger Baudains set off from the Weighbridge clock tower in Town at 4am and followed the route of the Saffery Rotary Walk along the coast, eventually arriving at the Imperial Hotel on the west coast 12 hours and 22 minutes later at 4.22pm.
So far he has managed to raise £980 for the charity.
Mr Baudains was accompanied for the entire length of his walk by Mark Prevel, an experienced long-distance walker who has undertaken a series of endurance challenges since being diagnosed with emphysema in his 30s.
He was also joined by some of his family for the final section near Pleinmont.
Speaking after reaching the Imperial, where he was about to have a well-deserved pint, Mr Baudains said the day had been ‘hard’, with the sun beating down on him and Mr Prevel for much of the walk.
‘It was so hot, and the elevation changes didn’t make things any easier,’ he said.
‘Having to go up and down places like Moulin Huet, Jerbourg and Saints Bay was difficult, but we got through it.’
The pair kept themselves in shape throughout the day on a diet of banana oatcakes and electrolytes.
However, with two miles to go, Mr Baudains said he hit a bit of a wall.
‘I honestly thought to myself “I can’t do this”, but Mark put me back in the right head space. I took a few minutes just to compose myself and then we got going again.’
Mr Baudains started long-distance walks following the death of his wife, Ann. They were married for 60 years.
‘I was struggling to sleep after she died, and that’s why I started, and it just carried on from there,’ he said.
‘I find it’s a brilliant way to keep my mind and body active and has been so good for both my physical and mental health.
‘I’ve met some brilliant people just by walking. It’s amazing what you can do when you put your mind to something.’
Mr Prevel, who completed a million-step challenge last month, was in awe of Mr Baudains’ achievement.
‘Doing challenges like this are very individualistic,’ he said.
‘You really have to focus on yourself and not compare yourself to what others might be capable of. Roger was incredibly determined to get it done and I’m just so pleased for him. He’s a true hero.’
