I’m in a similar boat… I decided to go into business with the guy who coached me through two IM’s and he is my main reference for questions, overall philosophy, etc. He and I talk multiple times a day and there is rarely a day that goes by when I don’t learn something new.
With that being said, he is not my only resource. I’ve met a few coaches on ST who are kind enough to answer the occasional question (I try not to bother them too much) along with some other coaches I’ve met over the years. I’m also always reading books on swim, bike, run asking questions, etc. I figure just about everyone I meet knows something I don’t and it’s up to me to figure out what that is.
In terms of certifications… I spent probably close to $1500 on a USAT level 1 cert last fall (travel, hotel, class, etc) and it was a complete waste of money. The presentations were iffy at best and I learned very little. The exam can be completed using the pdf “textbook†they give you and doesn’t actually require you to learn anything. A couple of highlights from my cert:
He spent an hour showing us how to analyze pedal dynamics on a computrainer. I don’t have a computrainer, nor does anyone I know. I don’t see how this “practical†actually applies to anything most of us do since none of us have the equipment to put tbis knowledge to use and it is a dying platform.
In the discussion of aerodynamics I was told that it’s always faster to have your bottle on the seat tube. Behind the seat is a terrible place. A minor issue, but one that bugged me.
I asked about baseline testing in cycling (ramp test vs 20 min test, vs 8 min test, etc) and was told that was too complicated of a question for that class… he then spent 90 minutes teaching us how to evaluate running form using the Pose method. Now I’m not an expert on running technique, but it seems to me that it requires more than an hour and a half to be able to diagnose issues and offer suggestions for athletes in a safe and knowledgeable manner.
I could go on, but those are a few that come to mind as I sit on my coach waiting for dinner.
In short, find a mentor, never stop asking questions, and don’t bother with a certification. I doubt I will renew mine.
