Friends Michael Neaverson (17), of Long Sutton, and Jack Robinson (17), from Spalding, took on a challenging hike from Derbyshire to Scotland to raise funds for Teenage Cancer Trust (TCT).

Jack completed the walk in 16 days, although Michael was unable to finish after injuring his ankle 30 miles into the 270-mile trek.

But determined Michael, whose brother Joe is fighting leu-kaemia, managed to soldier on for another 70 miles before stopping short of his goal in Hawes in the Yorkshire Dales.

He said: “I originally got the injury playing rugby a few months ago and although I kept going it was getting worse and had swollen a lot.

“Despite that and the fact that it snowed much of the time so we couldn’t see where we were going I really enjoyed what we did.

“Next year after my exams are finished I am going to give it another go.”

The pair, who are studying A-levels at Spalding Grammar School, are looking to raise as much money as possible for TCT, which helps sufferers such as Joe, who is receiving treatment at Addenbrooke’s Hospital in Cambridge.
