This is a biography of Eric Liddell, the world record holder of the 400 metres in the 1920s who made headlines by refusing to race on a Sunday. He made a switch from 100 metres to 400 metres, and triumphed. Liddell brought the same singleness of purpose to his faith as to his running. This book recounts his career as evangelist and missionary in China, his unassuming and selfless character, and his delight in practical jokes. It draws upon interviews with Liddell"s surviving family and friends, and also upon material from contemporary magazines and letters. Liddell died of a brain tumour in 1945 in a Japanese internment camp.
