Here’s the official video from the 2010 Cobble Wobble and some information on the event:

On the streets of a small somerset town, a group of riders from all corners of the cycling community came together for the second annual Frome Cobble Wobble to be in with a chance of becoming the Charge Bikes King of the Cobbles.

Pro riders like Chris Akrigg and Marc Beaumont fight it out against the locals up a 179 yard steep cobbled uphill sprint.

That looks like a blast!
