I've been a runner for about eight years (5K - marathon distance), currently rehabing from a tibial stress fracture. I've become more and more interested in the minimalist shoe concept the more I read about it, and am hoping that the combination of less shoe and proper midfoot striking can help prevent future injuries.
I've also been a musician for 25+ years, and I know very well how important it is to play with good technique. No matter which instrument you play, bad form can lead to all sorts of injuries. I've known my share of musicians who actually can't play anymore, or have to severely limit their playing, due to injuries sustained by long term performance. It makes sense that running would be the same way... you don't just go out and do it, mindless of technique. Well, you CAN, but... it likely will catch up with you. I want to be that 65-year-old you see running around the park someday. I hope that becoming mindful and aware of good running technique, and incorporating it into my own running, will allow me to get there someday!
