From very early on in Top Gear's life the phrase 'We decided to have a race' has appeared often. Some of the races have been brief, and some have been simply epic. Matt LeBlanc, one of the fastest ever celebrities round the Top Gear test track, presents a selection of the greatest and most entertaining races from the past 13 years. Matt LeBlanc guides us through another batch of races, including an Alfa Romeo 4C against an amphibious ATV Quad in the Italian Lakes, a four-way race across London and a Porsche 911 Turbo vs the unstoppable force of gravity.
