Steve Rulton from Great Cornard run 10 marathons in ten days - completing the Great Barrow 10 in 10 Challenge.
Steve entered the epic event - which involves marathon courses starting and finishing at Great Barrow, near Bury St Edmunds - to fundraise for Suffolk Accident Rescue Service (SARS) and Cancer Research UK.
“I wanted to raise money for a local charity like SARS as well as Cancer Research UK.
“I had heard about them through my work at Sanofi in Haverhill, and I am glad I have been able to help in some way.”
Once the donations have been totted up, Steve hopes to have raised nearly £2,000.
He bolstered his fundraising on his second marathon by completing the 26 miles dressed as a smurf.
SARS operations manager, Ben Hall, said: “I’ve met Steve a few times now and he is a lovely guy.
“This is an amazing effort, and an incredible challenge. We feel really honoured to be a beneficiary from all his sweat and hard work.”
Steve’s achievement is even more impressive considering he only took up running three years ago after being inspired by his wife Tracey, who had joined a local gym.
Steve ran the final marathon, accompanied by his daughter, and finished with an overall event time of two days, eight hours and fourteen minutes.
Steve is a member of the running club Sudbury Joggers and wants to be a member of the 100 marathon club before he reaches his 60th birthday.
“This was the toughest but also the most enjoyable challenge I have undertaken so far, so much so I will be doing it all again next year - minus the smurf outfit,” he added.
