Aaroncc, thank you for that invaluable tip! I had never heard of the sport of pedestrianism before, so I looked it up on Wikipedia:
Pedestrianism was a 19th-century form of competitive walking, often professional and funded by wagering, from which the modern sport of racewalking developed.
I, also, originally thought this mystery man was a boxer ... until I saw the cleats on his shoes.
I think you've solved the mystery!
