Shillito Park has one of the better dedicated paved multi-use trails in the area. At 2.4 miles, you can get quite a workout by just staying in the park. There are also several entrances where you can utilize either neighborhood streets or the sidewalks on Man O War and Reynolds Rd to extend your walk/run/ride for as far as you could want.
The park has so many other recreation opportunities too. I use the tennis courts a lot, but there is also a pool, ball fields, and baseketball courts.
If you are a train buff, you can see, on average, maybe 5 trains an hour pass by on the tracks between Fayette Mall and the park.
