The fastest time to ascend the height of Everest by box jump is 22 hr 18 min 38 sec and was achieved by Jamie Alderton (UK) in Bognor Regis, UK, from 29 to 30 November 2019.
Jamie has wanted to be a Guinness World Records title holder ever since his mother bought him his first edition of the annual aged eight. His aim was to find a record that had never been attempted before and would push him to his very limits. All in order to raise as much money as possible for local children’s charity, Chestnut Tree House.
He allocated twelve weeks of training towards the event he dubbed "Box Jump Everest". He began with an hour of box jumping which steadily increased through the weeks until he could comfortably jump for eight hours straight. As well as the specific box jumping sessions he built up his cardiovascular endurance through a mixture of long runs and swims.
Training for the event was one of the hardest challenges he had ever faced. The human body is not naturally built for long endurance sessions of plyometrics so it took an extended period for his lower body to strengthen and adapt to the training.
As prepared as he was after twelve weeks of training the actual attempt threw up it's own challenges. Nine hours in he injured his calf and his quad started to spasm. He had to resort to getting physio treatment between jumps in order for him to continue.
After completing the attempt it took three days to walk properly. It was a further two months until his tendons and ligamnets fully healed and he could get back to his normal training regime.
Despite the lengthy recovery time Jamie is now looking ahead to 2021 when he intends to break another record and hopefully surpass the £22,000 he managed to raise for his charity. He just needs to find something more impressive.
"If I could tell my 8 year old self he is going to be in the book when he’s older for box jumping Mount Everest I don’t think he would believe me"
