Speed with Guy Martin

The motorcycle racer joins forces with endurance expert Jason Miles to determine how far a tandem can travel during 24 hours of non‑stop pedalling. Their goal is to measure the maximum distance achievable on the tandem in a continuous day‑long ride.

Tandem is a programme presented as a single episode, falling under the broader category of television programmes. It is billed simply as an episode‑length feature, offering viewers a focused look at a specific challenge without extending into a series format. The core of the episode follows a professional motorcycle racer who joins forces with endurance specialist Jason Miles. Their shared aim is to determine the maximum distance that can be covered on a tandem bicycle when ridden continuously for an entire day. Together, the racer and Miles set out to test the limits of human stamina and coordination on the two‑seater bike. By pairing the racer’s high‑speed experience with Miles’s expertise in long‑duration effort, they hope to gauge how far the tandem can travel when pushed without pause. The experiment is structured around a strict 24‑hour window of non‑stop pedalling. Throughout that period, the duo maintains a relentless rhythm, recording the mileage achieved as the primary metric of success. The episode documents their progress, the practical challenges of staying upright for such a length of time, and the final distance logged at the end of the full day.
