The wet weather failed to deter hundreds of cyclists who hope to raise more than £12,000 for charity.
A total of 420 people - which included some 150 children - took to their bikes for the Cycle Together event, at Sandringham, to raise money for the Leonard Cheshire Disability.
Organiser Phil Davies said: “The ride started at 8am and between 7 nd 9am, it was raining solidly,” he said.
“We have had a great turn out, maybe not as much as would have come if the weather had been different, where there were four similar events taking place locally on the same day.
“Saying that, we still had 280 pre-entries and 140 cyclists who entered on the day itself.
“There were loads of children who came with their parents and we had some fabulous feedback afterwards.”
Eighty-four cyclists opted to ride the full 100 miles, while 183 did 50, 81 did 20 and 72 completed the shorter distance of 10 miles.
Downham-based Alec Singleterry, along with his son Duncan and grandson Adam (11), who travelled up to take part from Sevenoaks, in Kent, completed the 50 miles.
Mr Davies said: “I’d like to thank the volunteer helpers and the local companies who made donations.”
