I am trying to find some legit running clubs in the Los Angeles area. I have been looking at three - Track Club Los Angeles, Santa Monica Track Club, and Nike Team Run LA. I know that SMTC has different levels of training/support, from beginner through professional, but I am unclear as to how one goes about becoming part of one of the more elite (but not professional groups). As for Nike Team Run LA, I don't see standards or even a website for reviewing criteria for admission.
Can anyone provide some insight into these three groups, which are the best, which are more realistic to get into, and other similar run clubs out there that I haven't mentioned?
