Despite having retired from the ring, heavyweight boxing legend Mike Tyson isn’t playing golf in his free time, instead he's still training. But surprisingly instead of working in the ring, he's been busy training racing pigeons.In a new interview with the former champ, Tyson talks about his upcoming Animal Planet show "Taking on Tyson" which follows him as he trains his birds for competitive racing.A typical pigeon race involves having the birds travel a certain distance, Tyson says sometimes up to 1000 miles depending on the breed, and tracking how long each bird takes to return home.
