The Santa Clara Trail is a really popular path for running, biking, and hiking. It's seen some recent trail maintenance, so a lot of the areas that were facing some erosion problems have been tended to. The trail is basically all uphill one direction and all downhill the other, so it's a great trail if you're ready to get in a workout.
