No, I am not saying don't 'get certified'.
The day, week or weekend you take your certification is worth the time investment even if it just confirms what you already know. You have like 40+ weeks each year to "gain experience" at the track with your athletes.
AND, it is during these certification courses that you make the "connections and friendships" that lead to both future jobs, and future collaboration. It is in these certification courses that you find like-minded passionate people in the sport to whom you can develop lifelong friendships, mentorships etc.
There is no NEGATIVE to seeking certification from people passionate to teach and share about track and field.
Cool story, bro.
