I primarily do cycling to commute. That said, I've signed up for a 5k this Dec. Will make sure to wear my heart monitor and see how I do.

You can definitely go out too hard in a 5K, it isn't a 400, 800, or 1600M effort, but if you aren't hurting and questioning your life choices the last mile you weren't going hard enough :)
