For context, Canadian cruiserweight contender Ryan Rozicki divulged the amount that he will spar before a fight. “It really depends on the fight and the notice but, for my last fight [a 12-round draw with Yamil Peralta in 2024], I did eight-to-10 rounds, three times a week,” he said. The 30-year-old’s camp lasted eight weeks – meaning he engaged in up to 240 rounds of sparring. He’s had 22 fights. Should he have prepared in the same way for each bout, that’s more than 5,000 rounds of sparring – and that’s before we get into the mathematics of his amateur career. It shouldn’t be a stretch, then, to estimate how many rounds of sparring a more experienced competitor will have engaged in.
