RNLI supporters had their bicycles stolen soon after they set off on a ride to raise money for the charity that saves lives at sea on 3 May.
Malcolm and Jan Craven wanted to support the work of Hunstanton RNLI, where their son Andrew, daughter-in-law Kate and sister-in-law Joy are all among the the volunteers.
They set off From Felixstowe in Suffolk, with fellow cyclist Julie Wright and support driver Andy Brown, planning to ride the 315 miles along an ancient Hanseatic trading route to Beverley in East Yorkshire.
The four friends from Spalding in Lincolnshire set themselves a £500 target for their seven-day spell in the saddle.
But after making an overnight stop at a hotel in Lowestoft on Friday 3 May, they woke the following morning to find Malcolm and Jan's bikes, which were worth thousands, had been stolen.
'We were doing fine until we got our bikes pinched on the first night,' said hotelier Malcolm, 72.
'It was a bit upsetting, they bolt-cropped the cable to steal them, we think it was opportunist. They also broke into a golf course next door.'
Malcolm added instead of continuing their ride around the coast through Norfolk the following day, the Cravens had to return home to collect replacement bikes and write off 50 miles from their ride to make up for lost time.
But by Bank Holiday Monday, they were back on schedule, arriving at Hunstanton RNLI after being met by fellow Craven family members who volunteer at the Norfolk station, who escorted them on the final few miles.
Andrew, Malcolm and Jan's son, is a member of both lifeboat and hovercraft crews, while his wife Kate is the station's water safety officer and also leads its visits team.
Kate's mum Joy Roberts also volunteers at the station's souvenir shop.
Paul Stuart, one of the deputy launch authorities at Hunstanton, was on hand to greet them along with station mascot Stormy Stan.
'It's absolutely brilliant that they've kept going despite what's happened,' he said.
'It's not the first time they've done something for us, we're so grateful for their efforts.'
Back in 2017, the four friends raised £7,500 towards the RNLI's lifesaving work by riding from Land's End to John O'Groats.
