Thanks for posting. My change in gait has been revolutionary - I went from being able to run no faster than a 10 minute mile, to reliably running 3 miles at a 8.5 minute pace, without significant pain afterward, too. (although lately one of my knees is starting to bother me). I know that's not very fast compared to real runners, but it's pretty damn fast for me.Some interesting tips, related to the conversation about gait a while back: https://www.runnersworld.com/personal-best/4-ways-to-master-your-running-form
