On 1st June 1809 Captain Robert Barclay undertook what was then the greatest sporting feat ever attempted - to walk 1000 miles in 1000 hours for 1000 guineas. Six weeks later, exhausted and on the verge of collapsing, he completed his challenge and instantly became the most famous sporting figure of Regency times. Gentleman, pugilist, athlete, trainer and soldier - Captain Barclay's life was reckless, extravagant and thrilling. Enormous sums of money were won and lost on him and he himself earned several fortunes, though he was to die in deranged poverty. His remarkable story opens a window on the world of 18th century sport - a rough, dangerous and often corrupt world driven by money.
