Celebrity Race Across The World review: The way to win Race Across The World? A set of secret codewords, writes ROLAND WHITE

Scott Mills and his boyfriend Sam were more than a day behind the winning team in an early episode of Celebrity Race Across The World. But they came good when it mattered, and were last night first to cross the finish line.

The final wasnt just good news for fans of the Radio 2 presenter, but also for bus spotters, whose hobby has been cruelly neglected by television. (Would it hurt Michael Portillo to take the occasional double-decker?)

The final stage of the contestants journey through South America, from Argentina into Chile, featured more buses than a four-hour specialist Bus Channel documentary on the London Routemaster. There were at least five scenes in which the contestants bought bus tickets, which is nobodys idea of exciting TV.

It wasnt just tickets. There were atmospheric shots of bus stations, luggage being stowed, contestants climbing onto buses, and contestants sitting in their seats and enjoying the ride.

What Im excited about, said Jeff Brazier, is getting to Santiago and realising that they have really good onward transport connections.

If the first thing that excites about the capital of Chile is the onward transport links, you have almost certainly spent too much time on the road.

It was left to actor Kola Bokinni and his cousin Mary Ellen to lift our spirits. They took a taxi to Chile, and were rewarded by striking mountain scenery and huge salt flats.

This is the best road trip Ive ever been on, said Mary Ellen, excitedly. Imagine if we were taking a bus into the city.

We didnt have to imagine, Mary Ellen.

Race Across The World is one of those shows that shouldnt really work but somehow does.

Its often difficult to follow the action as different teams set off in different directions, and the result seems to depend entirely on luck. Also, its now almost impossible to watch a road trip without thinking that Clarkson, Hammond and May would be a lot more entertaining.

But it works because its pacy, it packs in a lot, and the camera doesnt hang around. And, of course, its fun to watch the travellers as their plans unravel.

As this was the final stage of their journey, everybody was in thoughtful mood. What you teach me is to be less serious, said Jeff to son Freddy, whose mother was the late reality star Jade Goody.

I love you a lot, said Freddy.

Scott and Sam also enjoyed a moment of reflection about their forthcoming marriage. If we got through the last 30 days, we can get through life together, said Scott.

Its no surprise that they won. They were so competitive that they designed a code to hide their plans from the other teams: M for the city of Mendoza, S for Santiago, BC for border crossing.

I dont think that would have given the Bletchley Park people too much trouble.
