The muscle-development slowing down fighters is bogus, when **generalizing** it. Top boxers run 5-10 miles most days. Then they jump rope, which helps running in a plyos way. They hit the bag- and that is very cardio, if you've never done it. Then the sparring is very cardio- Even a pro runner will gas in 1 rd when first trying it.

Great post.
This thread shows one of the oldest truths on Letsrun: If you suggest that a non-runner could achieve anything in the sport, bad runners will lose their panties arguing against it. This has happened every time a soccer player, basketball player, wrestler or boxer's ability has been posted.
It also shows that nobody here except ttc has a clue about boxing training. Take a moderately talented high school kid, say a 1:55 guy who could get to 1:50 with two years of real track training. Put him in a serious boxing program for two years and he will be at 1:53. A month of sharpening and he's at 1:51.
Real amateur boxers could go pound-for-pound with amateur sub-elite runners in VO2 max testing, that is for sure. And pro lightweights are not going to be far behind pro runners.
Sorry if that hurts anyone's feelings. They just train much, much more.[/quote]
I'd say he'd get to 1:52 after sharpening.
What people here aren't considering is that boxers don't just do "base training with some cross training" like any competitive distance runner. The session OP talks about is feasible because this guy also probably has a lot more pure power than your average sub-elite miler. The training for boxing can (depending on the gym) involve squatting several times a week, or doing burpee sets for half an hour, or kettle bell "rounds", etc, all of which build a huge amount of leg power. Combine this with a decent mileage base, and you get a session like the one described. Now could this boxer run the same times as a 4:0x miler across the board? Obviously not, as OP has said he probably wouldn't even be able to take a sub-elite guy in an 800m. But he would be able to smoke the miler in a 200m. Consider also, that the boxer is training not for a steady effort (1 mile at x pace) but for INTERVALS (12 rounds). His training is intended to make him a master at recovering between bursts of large effort. This will also give him an edge over the hypothetical sub-elite miler everyone seems to want to compare him to. As a boxer, he is pre-sharpened. He already has better power than the miler would develop by the week he peaks, making this session very possible for a 16:46 5k guys.
