It is very difficult for a runner of Kara's stature to join another group.
Elite athletes work real hard for a little exposure. Kara has achieved at that level already and it is difficult for others to "share the wealth".
She can't go to Mammoth because Terrance is busy trying to rebuild Deena's career and have Amy Hastings suprize the bigger names. How does Kara not disrupt both of those thing?
She can't go to Hansons because Desi and that group thrives on being "under the radar". This is the exact opposite of Kara Goucher.
She can't go to Shumacher because that wouldn't play well with Alberto (Jerry's boss) or Shalane.
