A young doctor from Devon will tackle one of the toughest long distance running challenges in the country next month in memory of his dad.

Jack Edwards from Okehampton is taking on the Dartmoor 500 ultra marathon on June 5 to raise money for charity.

His target is to run to every tor on the moor over 500 metres above sea level in a single day. 

That’s 52 tors and a distance of 105 kilometres (65 miles) and about 2,500m of elevation.

Jack is hoping to break the existing record of 15 hours 56 minutes. 

He has already raised more than £7,500 in sponsorship for local charity FORCE, who supported his dad Mike when he was diagnosed with terminal bowel cancer in February 2020.

Mike died in April this year and the memory of a “perfect father” has inspired 28-year-old Jack to undertake this remarkable test of strength and stamina.

“Dad was incredibly positive from day one of his diagnosis. He was a gentle, humorous, lovely man,” said Jack, a doctor in the Accident and Emergency Department at Musgrove Park Hospital in Taunton.

Mike was a land agent who managed nature reserves on Dartmoor so Jack’s choice of challenge is particularly poignant.

He’ll start and finish at the Warren House Inn, setting off at 5am and aiming to complete the distance before 8:56pm.

“This is different from anything I’ve ever done before,” said Jack. “It’s certainly the biggest thing I’ve ever done.

“People say that running an ultra is 30 per cent training, 30 per cent nutrition, 30 per cent mental attitude and 10 per cent luck!

“I’ll just take it one kilometre at a time. It should be an amazing day.”

The furthest he’s ever run before is 93 kilometres but he’s confident of going the extra distance and will have support along the way with friends running sections with him.

Family and friends will also meet him around the course to offer encouragement and keep him fed and watered.

It’s been a team effort since Mike and Jack began planning for the event in February, a logistical as well as a physical challenge.

One of those logistical elements forced him to switch the start to a day later than originally planned due to scheduled live firing on the Merrivale military range.

“I thought it was a big enough test without having to dodge bullets as well,” joked the former Okehampton College student, who trained at medical school in Exeter, Plymouth and Truro before working in hospitals in Glasgow and Bristol.
