Ditto. If you're wasting your time during your off season doing mostly speedwork, you won't last long. The most important thing you can work on is your aerobic base (cardiovascular wise, that is). If you have a crap base, you will be able to do speedwork, but you won't last long!

Follow Friel. He knows what he's talking about, and he's certainly more knowledgeable than anyone else here on the forums that might tell you otherwise! (no offense to anyone, of course!)
