Elation followed some self-doubt when a dad cycled up Sidbury Hill for the 51st time in a day to complete his ‘Everesting’ challenge on Saturday.

It took Tim Hammond nearly 16 hours to climb all 8,848 metres of the world’s tallest mountain – and ‘bizarrely’ he covered 193 miles within the confines of the Sid Valley.

His family held a bake sale and friends accompanied him for various distances to keep him on track, with Sean Faulkner joining him for the first half of the challenge.

“It went well,” said Tim, who was fundraising for type-one diabetes research charity JDRF after his 15-year-old son, Conner, was diagnosed with the condition last year.

“I had a lot of help. A good dozen people I ride with did stints with me and kept my mind occupied. Some did one climb, some did a few, some did a half-dozen.

“I covered 193 miles. It’s bizarre – people said if I’d gone in one direction, I would’ve gone a hell of a way. I’m not going to be rushing to do it again in a rush but it’s something I can tick off my list!”

Everesting is a popular pursuit in the cycling community and involves climbing the equivalent height of the mountain on a given hill in a single day. Once Tim logs his time online, other people will be able to try to beat it.

He started at 3.45am and did not finish until 8.30pm – 6,355 calories later – but managed to keep a steady pace throughout the day. He actually exceeded the height of Everest, climbing 8,968 metres.

The 35-year-old added: “The hardest bit was the middle, between 30 and 40 climbs. I was on my own and really tired but I still had a long way to go.

“When you get into the last dozen you start to think you can do it, but in the middle part you start to doubt yourself.

“It felt good to finish, it was a mix of relief and elation.”
