Alright, I'll lay it all down. I'm in High School (I know). In between sports, and I want to start running in general. I need to lose some weight and get in shape (5'10" and 175, just a bit big). So, I've started running. Well, I'm in the process. Last night I ran 2 miles in 22 minutes. Tonite I ran 4 miles in 32 minutes. The thing is I'm terribly sore. I know this should be expected but is there any way to reduce this? Its just my legs (duh) and its my calves and my thighs that hurt the most. I've been stretching about 5 minutes before and after, anyone have any good links to specific stretchs or what not? Also, this wasn't nearly as bad today as it was last night, but my chest starts to cramp. On my left side of my chest, I get this horrible crap. It was pretty fait tonite but still there, however it was very noticable last night. I usually eat about 3 hours before I run (Eat at 6:30ish and run at 9:30ish) is that enough time or is there something else? Thanks a ton By the way, I know this is going to sounds so pathetic but if anyone is considering getting the Nike+ system, it really helps. I payed 90 for my shoes (Nike+ Moire), 75 for a nano (1GB, new) and 30 on the little sensor kit and its really helping me monitor my progress and show how far I've gone etc.
