If road cyclists are so convinced that their skinny tires and aerodynamic bikes make them superior, why do they always seem to be the ones struggling to keep up on long, hilly rides? Whats the secret to building endurance for better bike handling when youre already on a bike thats designed to be as efficient as possible? Do you guys just not ride enough, or is there some magic training plan that Im missing? And while were at it, can someone explain to me why so many road cyclists seem to think that doing a few sprint intervals is equivalent to actually building endurance? Ive seen guys who can barely make it up a 5-mile climb without needing an oxygen tank, but they can do a 20-second sprint like its nobodys business. How does that translate to real-world endurance?
