Two fitness fanatics will take on a gruelling endurance challenge to raise money for Papworth Hospital.
Martin Arnold, 29, and Ben Nolan, 24, will tackle 120 miles on cardio machines at Fitta Bodies gym, Bury St Edmunds.
They were inspired to help out the Cambridgeshire facility after Martin’s father, Mike, was given a triple bypass there last Christmas.
Martin, who lives in Bacton, said his father was given first class care.
“The team at Papworth are incredible and do an amazing job. We are so thankful for everything they have done for my dad.
“They have given him a second chance, which is why we want to raise as much money as we can to support the work they do,” he said.
Mike, who owns Vogue Flooring and lives in Bury St Edmunds, has also played his part by exceeding doctors’ expectations for his rehabilitation.
Martin, a lab supervisor who also works as a personal trainer, said he expects them to burn more than 10,000 calories in the 10 hour challenge, and lose between three and four pounds in weight.
They have been helped by Anglia Sports Nutrition, who have provided cut prize supplements and energy drinks for their training, and Fitta Bodies have been very supportive, according to Martin.
The pair hope to raise more than £2,000 from the stunt, with nearly £1,400 already raised.
