Guy Martin has broken many Records and several 'World Records' (along with a few bones too), but this time, the danger and tension mounts to a whole new level (or Decline !). Guy will be swapping his customary two wheels with an engine for '4 Wheels' but with the only driving force being gravity and the chance to break yet another 'World Record'. Guy attempts to build and race the world's fastest soapbox racer, by creating a unique design with help from expert designers and engineers from Sheffield Hallam University. To supplement this, Guy will be training with the Team GB women's bobsled pair and also a very strong woman ... pulling a lorry. (all in the name of science).
