Y'know, I've been really aware of how Chi Running has helped my knees, and combining it with some of the things I'm learning in Yoga is definitely helping me improve my form in many ways, and I'm pretty sure it's helping me get faster.

But I hadn't thought about how the one-legged drills and such actually let me run more slowly when I want to. A couple of years ago I doubt if I would've been able to maintain the 10:40-11 minute pace I use for my long runs, now, without completely battering my hips, spine and shoulders.
