Long distance running is still part of the American Infantryman's diet, but we do more stress shoots and road marching than in years past. Guess what happens in firefights? Sprinting; not 5 mile runs, and guess who makes it up the hill to engage Al Qaeda or Taliban gunners hiding behind rocks at 9,000 feet? The meatheads who lift AND run, who can carry 200+ pounds plus the 75+ pounds of gear and ammo. I didn't cycle when I was in, but I was 6'4" 245 most of my career and ran between a 12 and 12:30 two mile time. Just because someone is bringing more grunt to the fight doesn't mean they don't have endurance to run those silly garrison 5-10 milers. That long distance garbage doesn't count for jack shit in combat anyhow.
