The Once a Year Club began in 1988 and each year features a sponsored cycle ride, auction and other activities.
Members gathered for the last time to officially wind up the club, which has raised £203,770 for CLIC Sargent.
Karen Anderton, who has run the club for the past 10 years, said: “It’s amazing when you think about it – it’s a lot of money. We’re over the moon we’ve raised so much."
The club first began with a handful of riders, organised by Ray Isbell, raising funds on behalf of Chris Lethbridge while his daughter was receiving treatment for cancer.
The last few rides have left from Marazion, where Mr Isbell now lives, but are still supported by veteran participants from Helston.
CLIC Sargent Fundraising Manager, Georgina Reed, said: “We would like to thank everyone involved with the Once a Year Club including; organisers, cyclists, local businesses who have supported the ride, and volunteers.
"The club has raised an astounding amount that has and will continue to make a huge difference to the lives of children and young people with cancer.”
Georgina cotinued: “Special thanks to Ray Isbell, John, and Karen Anderton who have organised Once a Year Club events throughout the past 26 years.”
