Titch thinks a week away is just what the boys need, so he proposes a 700km off-road motorcycle ride in Iceland.The team has had a busy summer, and Titch thinks some rest and relaxation is what the boys need. A sun lounger in Greece isn't his style, so he proposes they do something a little more challenging - a 700km off-road motorcycle ride in Iceland.The scenery is stunning. At this time of year though they are likely to encounter snow, and motorcycles and snow don't mix. Could bolt-on skis be the answer? The boys set about designing and building them, but with only time for a brief - unsuccessful - snow-dome test before heading to Iceland, they are very much entering the unknown.At the last minute Billy receives some shattering news from the doctor: a fractured bone in his hand, sustained while racing at Weston Beach, means he can't ride a motorcycle for six weeks. However, every cloud has a silver lining, and in this case it comes in the form of a giant 4x4, which means Billy can still participate.
