Fresh from his 206-mile challenge back in March, which culminated in the Bath Half Marathon, Radstock runner, John Reynolds, has been back out on the road again, this time as part of his series of Coast to Coast challenges.

On Good Friday, John set off on his ninety-mile route, which was following Hadrian's Wall from Bowness-on-Solway through Newcastle-upon-Tyne and finishing at Carlisle. He was joined by fellow runner, Laura Derby-Jones, from Oakhill, who has been upping her mileage thanks to training alongside John, but went from a huge fifty miles to ninety on this particular challenge. The pair went without sleep, finishing 22 hours later.

Her daughter, Maisie, who had joined John at the end of his 206-mile run in Bath and also ran to school alongside John that week, joined them both during her school holiday for a one-mile stretch along Hadrian's Wall. Ever since her experience in March, Maisie has become a very keen runner!

John has been sending photographs of his progress to local schools, many of which he visited whilst taking part in his challenge in March, to promote the importance of healthy bones on behalf of the National Osteoporosis Society, based in Camerton. Following his visit, the pupils at Maisie's school, Oakhill Primary, worked out the distance it had taken John just to learn to walk again, after the effects of radiotherapy, and ran it. In December, John also underwent surgery for a hereditary heart condition, but says he has never felt better. "This was one of the best runs I have ever done, the weather, scenery and the countryside was amazing. You can see for miles and at night the skies are so clear with stars, we didn't even really need head torches. It was cold though and got down to about minus two in places.

"The terrain was also really tough at times, but it was wonderful to be out in the wilds. I had an ankle injury a couple of weeks ago, but I ran through it – it is still working, thankfully! Your body will throw anything and everything at you to get you to stop. "Laura and I were both exhausted by the end of the challenge, finishing about 4.30 a.m. The local owners at the campsite said the military could complete the route in 26 hours and once they realised we had never been before and were navigating the route for the first time, they bet us £10 each for our charity that we wouldn't beat that time. We should have got everyone in the campsite to place a bet!"

John will now be taking a two days off to plan his next route. This challenge was almost a 'warm-up', as he will be setting off for Scotland at the end of May, running a route of 150 miles from the North Coast through the East Highland Way, visiting Ben Nevis and Fort William. He will be completely on his own, carrying his own supplies and navigating his way using GPS, recharged using solar power.

"It is a massive, massive challenge, but I am really looking forward to it," he says. "Psychologically, it will be hard too, running alone. But I have had really lovely letters from everyone who has been following my story and seen me out training – the support gives you a tremendous boost!"

John is hoping to run his Scottish leg of the Coast to Coast challenge in aid of the British Heart Foundation and the RUH. "They did a marvellous job with me and to run for them would be a big thank you to them for everything they did. I was really lucky."

Once he returns from Scotland, John will be taking part in a 100km run around Stonehenge and Avebury and a Coast to Coast run around Jersey and Guernsey. He will be taking on Ireland in September and will run from the Severn Bridge to Pembrokeshire in November. At the moment, he is documenting all of his 2014 running adventures and is looking to put it all together in a book which he hopes will be published at the end of the year. There really is no stopping him!
