I really enjoy Creve Coeur Lake Park. The walking/biking path is flat and you are often shaded by trees. I do have a bone to pick with the bikers though, as I almost got ran over by one. That irritates me.
We took the pups there a week ago for a nice long walk.
Our little urban jungle - -
Simon and Gus were pretty tuckered out in the end.
I'm planning on going back to Creve Coeur Lake for my 7 mile run. I'm starting to get pretty excited for the half-marathon!!
