15 February, 2200-2250, BBC Two - When it comes to danger, nothing compares to speed skiing. Despite all the risks, Graham will attempt to reach 200kph on the world championship course - that's nearly twice our road speed limit.

In a quest for speed, Ed then turns to Shelley Rudman, Olympic silver medallist in the bob skeleton to see just how fast he can travel.

Shelley and World Cup Champion, Kristan Bromley, have just two days to get Ed in shape and down one of the most challenging and dangerous tracks in Europe.

16 February, 1950-2000, BBC Two - Ed Leigh and Graham Bell push their bodies to the absolute limit by undertaking one of the most brutal mountain activities known to man. Our action men travel to New Zealand to scuba dive under six feet of ice.

22 February, 2200-2230, BBC Two - The mountains can be incredibly hostile and dangerous if you are left to fend for yourself overnight.

We leave Graham Bell to survive a night alone in the wilds of the Andes - while Ed Leigh leads a rescue party to find him the next day. Ed and Graham then learn, first hand, the dangers faced and the skills needed in mountain rescue as they join a team of expert lifesavers in the Alps.

23 February, 1950-2000, BBC Two - Ed Leigh finds the best off-piste snow in the Southern Hemisphere, hires a helicopter and test rides five completely different boards

1 March, 2200-2230, BBC Two - Pulling yourself up a wall of ice using just ice picks and crampons is both dangerous and difficult. Graham Bell and Ed Leigh find out just how difficult as they travel to the Exploradores Glacier in Chile and attempt to climb a 125ft glacier wall.

Ed and Graham then travel to the land of fire and ice and attempt to cross Iceland on Skidoos, a challenging adventure in a hot and cold world of geysers and glaciers.

2 March, 1950-2000, BBC Two - Ed and Graham explore the concealed dangers lurking beneath the Valley Blanche Glacier. Our intrepid presenters abseil down a deep crevasse and discover the hidden beauty of the mountains.

8 March, 2200-2230, BBC Two - Graham and Ed invite Duran Duran frontman, Simon Le Bon and his brother Jonny, to a frozen lake in Sweden in a quest for sailing supremacy - on ice.

They will fly across the ice on catamarans at speeds of up to 100kph in an exhilarating - and potentially very dangerous competition.

We then set Ed and Graham the challenge of accessing the highest mountain peaks using natural means only, such as animals and wind - instead of cable cars and helicopters.

9 March, 1950-2000, BBC Two - An action packed, adrenalin fuelled adventure as daredevil presenters, Ed Leigh and Graham Bell, take to the skies for a bird's eye view of the Alps as they paraglide over Chamonix.

15 March, 2200-2230, BBC Two - Fiona Bruce joins Ed Leigh and Graham Bell to tackle one of the longest and most challenging glaciers in the world, the Jungfraujoch in Switzerland.

Graham and Ed then travel to Chile, where they trek up one of the country's largest and most active volcanoes - the 2847m Villarica.

Despite hot lava rumbling beneath the surface the volcano is covered in snow, Ed and Graham take full advantage to ski down - taking care to avoid the steaming crevasses.
