We do have a trail that goes around the Zoo yet it's more of a walking trail. It does not have the "exercise suggestions" as you stated in the other fitness trails.
Thompson Park has a decent sized trail network, most of which are paved. Right outside the zoo there is a fitness trail that you can run and optional to stop at several fitness stations with bars, decline benches, wood beams, and more to do varying activities. There are signs posted at each station for exercise suggestions or you can do your own exercises.
If you mean trails you can run on, no.
