As someone who has a lifelong (or, at least post HS - I ran track and XC way back in the day) mantra regarding running as being "I only run when chased"

, I have been doing a lot more of it the last few years.
I've been looking into some options for improving my running form, technique, and efficiency, and 2 that I've found so far that seem interesting and promising are:
The "Pose" Method, by Romanov, and Chi Running, by Danny Dreyer.
Both seem focused on not overstriding, maintining high cadence, and bringing the heel up higher (towards yer butt).
Is anybody familiar with either of the above, or any other skill training or coaching methodology they could recommend? Thanks in advance-
(I'm also going to attend a Total Immersion swim workshop - I *suck* at swimming - conveniently located right in New Paltz, and am finally breaking down after all these years and getting a professional bike fitting as well)
