Titch embarks on a very personal build - a vintage custom motorcycle to honour his late grandfather who was a D-Day veteran and the inspiration for his own military career. Corporal William Cormack served with 45 Commando, the same regiment Titch would be a part of 50 years later. But this is more than just a build for him. Once completed, Titch wants to ride the machine over to the D-Day beach his grandfather landed on and pay his respects to the soldiers who took part in the Second World War.

But before Titch crosses the channel, there's an AC Cobra in Cornwall that needs the team's attention. Its owner, Ray, has been ill with cancer and has been unable to fix an engine fault so the beautiful car has been in pieces for the past four years. Titch and the team call in to see if they can get it running again.

Titch has a desire to re-enter an event he's not competed in since 2014 - the mighty Weston Beach motorcycle race.

With the four-mile sand course containing obstacles the size of houses, it is one of the most punishing beach races in the world. The three-hour endurance test takes its toll on riders and machines, and Titch's battered body - the result of years of Special Forces abuse - isn't as injury-free as when he last competed.

But if concerns over his own fitness weren't enough, he wants to make things even harder by entering on a vintage scrambler the same age as he is. Which will break first - the 47 year-old bike or the 47 year-old man?

In preparation for the race, it's not just the bike that undergoes a rebuild. Titch visits orthopaedic surgeon Charles Willis-Owen to see what, if anything, can be done about his damaged knees and ankles before the flag drops at Weston.

Titch is joined in the race by last-minute entry Billy. Titch may not be in the best physical shape, but injured military veteran Billy is attempting the challenge with just one fully-functioning arm.

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.
