At the north side of Mt Tabor park is a set of stairs that takes you to the top in 280 stair steps. A great workout that you can do walking or running as long as you can. At the top is a short loop ( 0.32 mile ) with level ground where you will enjoy mountain views as well as city views, all the while being surrounded by large douglas fir trees.
If you would rather forgo the strenuous stairs, you have the option of following roads or paths to enjoy this most beautiful semi-natural park that has so much to offer. At dusk you might hear a whoo-hoo from one of the resident owls.
As to the length of the route, and the elevation gain, divide it by four, because we did it four times, oops.
