Speed junkie, motorcycle racer and lorry mechanic Guy Martin loves pushing the boundaries of speed in search of a buzz. He returns with a second series of Speed with Guy Martin, taking on four new speed-based challenges. From racing a motorbike at altitude to trying to break the speed record for a hovercraft, Guy wants to find out what makes things go fast by getting his hands dirty in a range of unique engineering projects. To do this, he has to harness cutting-edge science, learn new skills and call on the support of some of the unsung heroes of British industry, using the best of our design and engineering talent. In the first challenge, Guy gets back on a bike to see just how far it's possible to cycle during 24 hours of non-stop pedalling. With the help of bicycle brainiacs Miles Kingsbury and Mike Burrows, the man who designed Chris Boardman's gold medal-winning Lotus bike from the 1992 Barcelona Olympics, he builds a revolutionary tandem and pairs up with his friend, endurance expert Jason Miles, to see how far they can push their bodies at the Extreme Environments Laboratory at the University of Portsmouth. In the build-up to the final record attempt at the historic Goodwood Motor Circuit, Guy also learns about the science of cooking for athletes with the Head of Nutrition at Team Sky, Nigel Mitchell, who instructs Guy to lose five kilos of weight and recommends a new diet regime. Guy also works out the best ways of relieving himself on the move to save vital seconds. As the day approaches for the record attempt, news reaches the team that Hurricane Bertha is approaching
