For the next six weeks Prior’s colleagues at employee engagement agency Involve will track his progress on a rowing machine in the office as well as measure their walking, running and cycling activity as he attempts to break the world record for crossing the Atlantic in less than 32 days.
Staff will also be given one of the company’s five core values, which each employee will adopt for two weeks before choosing another until Prior reaches the finishing line.
Prior, whose nine-year-old son suffers from the disease, is attempting to raise £100,000 in order to increase awareness.
Jeremy Starling, managing director at Involve, said: "James is doing an amazing thing for his son and we’ve all been inspired by his dedication and enthusiasm.
"We’ve always spoken to companies about leading by example and this is the perfect way for us to pull together as a team and re-ignite our passion and our values."
At the end of the six weeks, employees will vote for who embodied the agency’s five core values the most, with the winners flying out to the Caribbean to meet Prior at the end of his journey.
