Read the text. Then choose the correct answers.
The Pennine Way is a 469-kilometre walking path which runs from the Peak District in Derbyshire to just inside the Scottish border. Other trails go further, but it is known as the most challenging. This is because of the nature of the landscape, which is hilly, rocky and often very muddy. Some people see this trail as an opportunity to take a pleasant day's hike on a small section of the route, but eighteen-year-old David Lemming saw it as a challenge. ‘I’d come across a great account of hiking the whole trail, written a few years ago, and I was determined to do it myself. A friend was going with me, but he changed his mind. So I promised my parents I'd check in daily on my mobile, and I’d also post pictures on my social media page. I didn't feel anxious - I was just excited to get going.’

Things went perfectly for the first week. David made good progress and was really enjoying the experience. Since many people use the trail, he was constantly meeting fellow hikers, so he never felt isolated. 'But then it got really stormy,’ he says, 'so a lot of people gave up. I could go for hours without seeing anyone at all. But as long as I had my mobile, I wasn't really worried about anything bad happening.’

Unfortunately, something bad did happen. During a particularly heavy rain storm, David slipped in the mud, went off the edge of the trail and fell about ten metres down the hill. ‘I realised I'd broken my arm immediately, but I knew my location and thought I could still call for help. Then I found that my mobile had fallen out of my pocket. And when I tried to get up to look for it, I couldn't stand up at all. My leg was injured too.’

All he could do was to shout for help. ‘I yelled until my throat was sore,’ he says. ‘And nothing happened. But then I saw a head at the top of the hill - someone had heard me. A man came down, saw the state I was in and called for help. And really, that was the most amazing part of the whole experience. At the hospital, even the doctors were impressed at how much of the trail I’d covered. I felt really proud.’ Will he try to walk the trail again? 'Absolutely,’ he says. ‘It's a fantastic place, and nothing can keep me away.’
