At least six hundred and fifty people are getting on their bike for charity today - at this year's Great Weston Ride.

The 56-mile challenge from Bristol, through the Mendips and across the Somerset Levels to the seafront at Weston, is all in aid of the Prostate Cancer Charity, and other causes chosen by some of the riders.

Organisers say the event raised thirty thousand pounds in 2011 - making a total of fifty grand in it's first two years ... and they're hoping to double that today.
