If you ever feel guilty about spending too many inactive evenings supine on your sofa and drinking tea – a remedy is at hand - Top Dogs: Adventures in War Sea and Ice.  Starring the most inspiring and courageous men of our time – polar explorer Sir Ranulph Fiennes, solo-yachtsman Sir Robin Knox-Johnson and BBC World Affairs Editor John Simpson – they take us one step closer to death-defying adventures and breathtaking danger.

The idea is that each man introduces the other to their own domain – Sir Ranulph Fiennes leads the other ‘dogs’ around the inhospitable Arctic, Sir Robin Knox-Johnson makes them set sail on the stormy seas of Cape Horn and John Simpson guides the men around war-torn Afghanistan. Exhausting stuff.

The three-part series is dripping with drama – from John Simpson being evacuated from the Arctic with a nasty case of frost bite to Sir Ranulph Fiennes coming down with some pretty severe ’sea sickness’ as their 48-foot boat was rocked by waves larger than their houses, and the moment of terror when the three men hear the Taliban have organised an ambush for them as they return to the Tora Bora caves.

Not only this, but we hear that each dog has a wicked sense of humour – Friday nights just got even better.

Top Dogs: Adventures in War, Sea and Ice, a three-part series, airs at 9pm on BBC2 on 27 March, 3 April and 10 April.
