The mystery man threw off his disguise and started to run. Furious stewards gave chase. The crowd roared.

A legend was born. Soon the world would know him as 'the ghost runner'. John Tarrant. The extraordinary man whom nobody could stop. As a hapless teenage boxer in the 1950s, he'd been paid £17 expenses. When he wanted to run, he was banned for life. His amateur status had been compromised. Forever. Now he was fighting back, gatecrashing races all over Britain. No number on his shirt. No friends in high places. Soon he would be a record-breaker, one of the greatest long-distance runners the world has ever seen.

This is his true story: The Ghost Runner.
