Trev, Jo and Andy are about to storm 200 miles to France.

Listen to the adreneline-fuelled trip of their lives (except when they're in A34 traffic, obviously). It kicks off Friday 29th April from 7am on JACKfm.
The aim is to raise money for technology charity SpecialEffect, who help people with physical disabilities reconnect through the world of video games.
If you feel compelled to donate, the Just Giving page is the place to click next.
Here's some of the amazing work they do.
