Ep 4. World's Fastest Toboggan

In season 1 episode 4 of Speed with Guy Martin, titled "World's Fastest Toboggan," Guy Martin sets out to break the world record for the fastest toboggan sled. The current record stands at 83 miles per hour, which was set by a team in Canada. Guy travels to Lillehammer, Norway, the site of the 1994 Winter Olympics, to attempt to break the record on the Olympic bobsleigh track.

Before attempting the record, Guy meets with the Norwegian bobsleigh coach, who gives him some tips on how to handle the sled at high speeds. Guy also practices on the track with an experienced bobsleigh driver to get a feel for the twists and turns. Once he's comfortable with the track, Guy gets to work on designing his own toboggan sled.

Guy enlists the help of aerodynamics expert Dr. Ben Evans to design a sled that is both fast and stable. They settle on a design that is longer and narrower than a typical toboggan, with a curved front end and a sleek, streamlined shape. The sled is made from a lightweight carbon fiber frame and covered in a layer of foam to protect Guy from the high speeds.

Finally, it's time for Guy to make his attempt at the world record. He starts at the top of the Olympic track and hurtles down the icy slope at speeds of up to 90 miles per hour. The sled stays stable as Guy navigates the twists and turns, but it becomes difficult to control as he nears the bottom of the track.

Despite some close calls, Guy manages to stay on the sled and crosses the finish line at a record-breaking speed. The exact speed will not be revealed in this description, as we aim to avoid spoilers. Guy then reflects on his achievement and admits that breaking the world record was one of the most exhilarating experiences of his life.

Overall, "World's Fastest Toboggan" is an exciting and adrenaline-fueled episode of Speed with Guy Martin. Viewers will be on the edge of their seats as Guy attempts to break the world record and marvel at the sheer speed of the toboggan sled.
