Walter G George was a UK athlete from the late 1800’s, competing mostly in the mile and setting a number of world records. He had an unorthodox approach to training due to the limited time he had available to train while doing his apprenticeship to become a chemist. He set a world mile record of 4:10:12 in 1886, a time that stood until 1931 (and the track was wrongly measured; he actually ran 1 mile and 6 yards).
