Swimming VS Running

Oh, I run... I just grumble gripe hiss spit and complain while I'm doing it. (I have relatively big leg muscles and weak cardio) I don't hate it as much when my cardio is in a much better shape. Actually, I much prefer rollerblading, even when it kills my cardio. My 'lifetime' achievement with running is to run three 10-minute miles. This is about 7 years ago when I was in the best shape of my life, and used to speedskate (rollerblade speedskating) 30-40 miles a day. Right now, 10 minutes of running on a threadmill, and I'm gasping for air. But... *sigh* I keep doing it... how else is my cardio gonna get better. I think I'd much rather sprint 50x50 freestyle (lactic acid in shoulders permitting), but shoulders need a break. then again... I HATE running :eek: :rolleyes: :p
