As a recreational runner I suppose my primary goals are to maximize health benefits and minimize injury and long term wear-and-tare. My absolute pace doesn't really matter, I just want to see it improve over time. I know I have terrible running form, but I kind of view it as not owning a fancy road bike. Sure, I'm slower on my old mtn bike, but I'm burning more calories. Now I'm wondering if that's a bad philosophy for running, after watching videos of good runners I'm amazed how smooth they are. All my bouncing up and down has got to be hard on my suspension, and new struts are expensive.
