I just ordered two books from Amazon.com. ChiRunning (thanks for the tips) and Running and Breathing. The guy who wrote Running and Breathing says you can pretty much run, bike, swim or whatever as long as you want without exhaustion as long as you breathe right. So...we'll see! I think breathing is definately key with me, because I'm missing something. I know what you mean tri-Berkeley...I feel like I could walk faster too!! I need to find a way to keep from going anaerobic when I run. My HR climbs up to 170-175 and hangs out there. So literally I'm sucking wind the whole time. I think that's where the pain in my side is coming from. Hopefully these books will help. And hopefully I can kick this upper respiratory thing soon so I can get back to training. I've been lying low for two days now hoping that will help. And I stink of garlic (supposed to help...who knows!)
