A remarkable feat was achieved by a 15-year old schoolboy who won a coveted first prize in the annual Keswick to Barrow run - despite needing medical treatment during the course.

Max Hazlehurst, from Askam, was the first under-17 runner to cross the finish line with a time of six hours and one minute despite spending 25 minutes in an ambulance in Coniston due to a toe injury.

Max, who attends Ulverston Victoria High School, was running for CancerCare in Team Kemp, and explained his inspiration for running the K2B.

"I had a teacher at Low Furness Primary School who was really into sport and she decided she wanted to run a mile every day with years five and six, so we did that for a while, then she did a 5k run with us," he said.

"I hadn't done much running before that - I'd been active, played sports like cricket.

"She died of cancer, a brain tumour, and my grandad died from leukaemia, so I was doing it for them.

"I eventually want to be a PE teacher and just be involved in sport.

"This is the first time I've done the K2B and I'm already planning to do it next year - it's easily the longest run I've ever tried - I've got up to 24 miles in training.

"I've been doing track training and going out every weekend for a long run."

His dad Brian witnessed first-hand Max's ordeal, and spoke of his pride at his achievement.

"When he was at Coniston he was second in the race, he was flying, and then his injury slowed him up," he said.

"He was in Coniston by two hours 20 minutes so he was on course for under five hours but these things happen and with the build-up of lactic acid after having to spend 25 minutes in the ambulance, he found it a bit difficult to get moving again.

"He had a blister under his toenail, which is still hanging on by a thread now.

"The marathon part was fine for him, he was well up in the pack at that point, but the last 13 miles were really gruelling for him - he showed a lot of grit and determination to finish with that time, which was a great time anyway, coming 16th overall."
