A Gainsborough man raised over £700 for charity thanks to his multi-sport race efforts in July.
Stuart Grocock finished the Cleveland Steelman half ironman race, in a time of five hours 54 minutes.
The 42-year-old took on the 2km lake swim, 58 mile bike ride on a hilly course and a 13 mile running section and crossed the line in 110th position, in a field of 200 competitors.
“I achieved the sub six hour mark that I was after,” he said.
“And I raised £711 for Cancer Research, breaking my £500 goal.”
The race was a family affair for the Grococks, with Stuart helped out in training by Great Britain Duathlete Amy, and brother Steve who also raced in Cleveland.
Stuart told the Standard: “The weather, having been a heat wave all week, decided to start to rain just as the race started which actually was quite nice and a bit cooler.”
“However it did cost my brother Steve a third place overall finish as he fell off his bike whilst leading the race.”
The goodwill and support of those who sponsored his race kept him going through the toughest parts of the gruelling event.
“I would like to thank everybody who contributed to my Cancer Research charity page,” he said.
“I did remind myself at the nine mile mark on the run when I was virtually at walking pace that people had been kind enough to donate, so I must not give up.”
“The swim was the worst part as I had practiced in the river with Steve but had not factored in 200 people all trying to aim for the same bit of water.”
“I did stop at one point to calm myself down as I could feel myself panicking.”
Now the EMI Engineering worker may turn his attention to an even greater challenge.
He added: “I feel a bit flat now as the last few months have been about training, nutrition all geared for the race and now its over.”
“I have to decide now whether to go on next year to do the full iron man, that requires a lot of commitment to training.”
“We shall have to see.”
