THEY may be crazy but they are doing it for charity.
Twenty-four teams with a minimum of four riders will take turns riding for eight hours, led by six professional instructors who are expected to provide a tough ride for the group.
The ride will raise much needed funds for the Queensland Institute of Medical Research.
One team member braving the ride is Web-Sta Affordable Web Design's Karen Ahl, who confessed she was completely new to the RPM bike.
"I'm a little bit scared about it all, but it should be fun," Ms Ahl admitted.
Another rider jumping on for the cause is Gavin Douglas who was excited to put his enthusiasm for riding to good use.
Gavin has been involved with Conquer Cancer rides a few times now. He was moved to act for the cause after he sadly lost his cousin to bowel cancer, and was fortunate Fitness N Motion was happy to come onboard to support the cause.
"It's good to support charities close to home," he said.
Fitness N Motion franchisee and one of the riders who will be leading the pack, Sharon Cessford said she was pleased to be involved with the cause.
"We were going to organise a challenge for our members anyway so why not make it a worthwhile one?" she said.
The Fitness N Motion Ride to Conquer Cancer RPM Challenge runs from 7am-3pmon Sunday, August 5.
