Four gruelling multi-sport challenges have been completed by a Poole man – raising more than £5,000 in honour of a much-missed friend and colleague.

RNLI volunteer lifeboatman Rob Inett is celebrating his achievement in memory of fellow crewman Paul Singleton, who died from cancer in October last year, having spent 30 years saving lives.

“Originally I wanted to raise £1,600, representing £1 for every time that Paul launched on service with the lifeboat,” said Rob, who collected funds for Marie Curie Cancer Care.

“However having raised over £5,000 now I’m delighted with how well the fundraising has gone this year. I’ve had amazing support from friends and family, and a few local businesses such as Lake Yard, Wigmore Books and Dorset Catering Services, who have all been fantastic.”

The 32-year-old marine engineer from Hamworthy took on extreme physical challenges including an Ironman Triathlon, half-Ironman race, 12-hour non-stop static cycle challenge and an epic 11-hour mountain quadrathlon in Snowdonia.

This final challenge saw Rob and two close friends tackle a 60-mile bike ride, one-mile open water swim, three-mile lake paddleboard and climb to the summit of Snowden and back in atrocious weather, high winds and pouring rain.

“I was completely exhausted at the end of that one, but getting through it all with some wonderful friends has been a great experience,” he said.

On the summit he laid a photograph and message in memory of Paul, who died aged 52, from his crewmates at Poole Lifeboat Station. It said: “Loved and missed by all at Poole Lifeboat.”

Rob and Paul’s family met three local nurses from Marie Curie, who helped nurse him through his final months at home. He handed over a cheque for £5,125, enough money to fund 256 hours or 32 full nights of a nurse’s time, giving care to those living with cancer.

His fundraising will end on December 1. To support him go to justgiving.com/Rob-Inett
