In this three-part series in partnership with OS Maps, we take a closer look at GetOutside Champion Sean Conway’s National Parks Challenge — which saw him take on 15 marathons in 15 National Parks in 15 days — to learn what it takes physically and mentally to complete such a challenge and discover some of his highlights along the way.

Having completed a marathon in the Cairngorms and Loch Lomond and The Trossachs National Park in part 1, we catch up with Sean again as he continues his journey south and across the border into England. You’ll also find details for each of the routes Sean ran to take them on yourself.

Reality Bites

Despite a ruthless ability to chase the distance, as Sean Conway chipped away at 15 back-to-back marathons, across some of the most challenging landscapes the UK has to offer, the tax man would never be far from his heels. Succumbing to exhaustion, it seemed, was surely just a matter of time.

‘Running is so hard. Even the fittest people in the world get injured while running,’ explains Sean. ‘That meant I needed to work on injury prevention, which just means putting in the time on the legs. But for the National Parks project, it wasn’t about staying injury-free, it was about knowing the difference between a long term injury and what’s just a niggle.’

Making his way south through the United Kingdom, one marathon at a time, Sean was steadily racking up the distance. Five deep with over 130 miles under his belt, without proper facility or opportunity to recover, the enormity of the challenge was starting to stack against him.

‘The driving took its toll on my recovery and the middle five were really tough. I had really tight muscles that were pulling my knee all over the place,’ he remembers. ‘In England I found the Norfolk Broads the hardest. Being entirely flat meant I didn’t walk much. On the hilly routes of Northumberland, the Dales or on Exmoor, I’d walk the steep sections and use different muscles but on the flat you just pound the knees all day. That was hard. Also when it’s flat, you can see how far you need to run and that was tough on the mind.’

By the time he had reached the south of England, the accumulative strain on Sean’s body and mind aligned perfectly with the hottest days of summer. With seven marathons still to run, he knew he’d have to dig deeper.

‘Growing up in Africa means I quite like the heat so it doesn’t stress me out, but my performance goes down drastically,’ says Sean. ‘When it got really hot, I needed to drink about six litres of water a day and make the effort to really increase my salt intake. To drink that much, of course I needed to carry more water which means I ran slower which means I’m out longer which means I need more water again. It was a downhill spiral from there.’

Having so many people join me really spurred me on. The ultra-running crowd is such a good bunch of people

The Power of Community

Anyone who has dipped as much as a toe into endurance sport or even a long day on the hill knows the loneliness of the pursuit. Add to that a niggling injury, exhaustion, a battle with dehydration and the small issue of seven marathons still ahead of him, and the sense of isolation amid the task at hand, saw Sean depleted and lacking motivation.

Luckily, the running community had his back. In the South Downs, about 40 local runners who’d been following his progress online showed their support by joining him out on the trails of their local hills. Something he still remains thankful for today.

‘They came at the perfect time, I was struggling with the mileage a few days before that and my right knee was in pain. But having so many people join me really spurred me on. The ultra-running crowd is such a good bunch of people,’ he says. ‘I was worried that I’d spend the entire marathon answering the same questions and getting bombarded, but everyone just actually wanted to come and run. It was great! And the few people who did want to chat, we landed up having some fabulous conversations about anything and everything. I even ended up getting a massage from a runner that came to join me and that helped a lot.

‘Before these marathons I’d have done anything to avoid running in groups. I love running on my own, and I still do, but I now also really appreciate running with other like-minded people.’
