With a long line, if you call and she doesn't come, you can gently reinforce her recall, and then reward her for coming back.

Also sounds like she simply has a strong chase drive, so use this but convert it to play. Teaching her to chase and catch a frisbee will help a lot, you need to keep her focus on you and frisbee games.
