A top doctor is pushing the boundaries of charity challenges further than most.

He plans to climb, run, cycle and even kayak his way between the Three Peaks.

Dr Alistair Morris, a consultant paediatrician at Huddersfield Royal Infirmary, will scale Britain’s three highest mountains – but in a twist on the popular walking challenge he will also cycle between them non-stop on both road and mountain bikes.

Once at the foot of each peak he will be joined by a friend for a high speed ascent to the summit and back down to pedal on to the next one.

The epic adventure will see him travel through the night, grabbing only a few hours sleep where he can.

And his route north from Snowden to Scafell Pike and then Ben Nevis, will even see him switch from two wheels to a boat as he paddles 11 miles across Windermere, England’s biggest lake.

Dr Morris, 41, who lives in Hebden Bridge, does have some form to see him through the tough feat – he is a ranked as the UK’s 16th best adventure racer and has placed highly in national and world events.

But even with a background of competing in week-long races across the wilderness he admitted this one was going to be tough.

The route is still being finalised but he says it will take roughly 466 miles of cycling and a marathon’s worth of running.

“I wanted something that was recognisable as a Three Peaks challenge but a bit different,” he said.

“I do endurance racing so I wanted to add a bit of a challenge to it but it’s not going to be easy.

“I will probably only get a few hours kip at night as I plan to do the route non-stop.”

Dr Morris is taking on the ultra-endurance challenge on June 1 to raise money for a host of cancer charities, some of which supported his partner during her breast cancer treatment.

Along with Calderdale Royal Hospital’s Macmillan Unit and the Macmillan Cancer charity he will donate some cash to Leeds based The Haven, which has a hardship fund for cancer patients.

He added: “When my partner was there she met people who couldn’t even afford the taxi home, which is awful.

“Having money problems while you’re suffering with cancer is terrible, you don’t realise how privileged you are.”

Dr Morris is unsure how long his extraordinary challenge will take and so has launched a competition for sponsors to guess his total time.

The closest guess will win some outdoor equipment donated by top sports leisure firms.
