Comic Relief: Find out about Billy Monger's epic challenge

Young racing driver Billy Monger has taken on an epic challenge for Comic Relief.

He's doing a gruelling 140-mile triathlon-inspired event where he walks, kayaks and cycles across England...in four days!

That's hard work for anyone, but it's made even more of a challenge by the fact that Billy lost both legs in a crash four years ago.

We caught up with him to find out how he's getting on.
