Speed with Guy Martin

In the second adrenaline‑charged stunt of the programme, the rider sets his sights on breaking the world record for riding a motorcycle on water. To attempt the feat, he enlists the expertise of a Cambridge professor, whose academic background lends scientific rigour to the project, and works alongside marine engineers who design the necessary equipment and support systems. Together they devise a plan to keep the bike afloat and stable while it powers across the surface. The challenge pushes the limits of both rider skill and engineering, aiming to achieve a landmark record that has never been documented before in this daring experiment.

A racing enthusiast decides to take on a challenge: to achieve flight using nothing but his own muscle power. He throws himself into the project with the aim of proving that a human can power an aircraft fast enough to set a new benchmark. He’s determined to push the limits of what a single person can generate. To realise this ambition, he partners with engineers from Southampton University. Together they design and build what they hope will be the fastest man‑powered aircraft the world has ever seen. Their collaboration mixes his racing‑inspired drive with the university team’s technical expertise, aiming to create a machine that flies solely on human power at unprecedented speed.

A keen racing enthusiast decides to construct his own prototype toboggan, aiming to push the limits of gravity‑powered speed. Using his own skills, careful engineering and determination, he's fashioning a lightweight sled designed specifically for rapid descent, hoping it’ll outperform any existing design. Once the build's complete, he's journeying to the Pyrenees, where the steep, snow‑covered slopes offer the perfect arena. There, he launches his creation in a bid to smash the current record for the world’s fastest gravity‑driven sled, seeking to prove that his homemade machine can outrun every competitor that’s come before, even still under the toughest conditions.

In this episode of Tandem, a professional motorcycle racer joins forces with endurance specialist Jason Miles. Together they set out to discover the maximum distance a tandem bicycle can cover when ridden continuously for a full 24‑hour period. Their partnership combines the racer’s high‑speed experience with Miles’s expertise in long‑duration stamina challenges. Over the course of a non‑stop ride they push the bike’s limits, recording how far they can travel without pausing. Both keep a steady rhythm, swapping seats to combat fatigue and logging mileage. The figures will show what two riders can achieve without a break, illustrating the endurance potential of a tandem under relentless pedalling conditions.
