A man whose life was saved by a lung transplant is planning to undertake the National Three Peaks Challenge to raise awareness of Cystic Fibrosis.
Oli Lewington from Irchester in Northamptonshire is to don his hiking boots and rucksack
in May as he seeks to climb Ben Nevis, Scafell Pike and Snowdon, the Northamptonshire Evening Telegraph reports.
Explaining his motivation, Mr Lewington said: "I feel that I owe something to my donor and their family for being courageous enough to donate the organs to me."
The 28-year-old - who also suffers from diabetes and osteoporosis as side-effects of his condition and medication - will be supported by TV personality Ben Shepherd, who he met at another charity event.
Shepherd was one of the group who climbed Kilimanjaro for Comic Relief in 2009.
While the highest peaks in Scotland and Wales are close to the towns of Fort William and Llanberis respectively, Scafell Pike is often climbed from Wasdale Head, a tiny hamlet with few facilities to deal with the influx of climbers each summer.
However, last year extra toilets were installed for the benefit of the climbers.
