It's the fourth annual "Breast Cancer Awareness Ride".

The event is sponsored by the Sports Den and the Trek Bicycle Company.

Riders can choose between a 10 mile and 25 mile ride.

Last year there were 151 riders, and this year, organizers are expecting more.

"We thought this was a great way to show our support and hopefully someday find a cure for these cancers that are out there", explains Sports Den owner Dennis Riedel.

Registration is $25 and all money raised will go to the "Breast Cancer Research Foundation".

Thursday is last day to register online, you can also register on race day.
