Starting at Hilltop Park runners climb to the top of little black loop trail and run through the beautiful trails within Black Mountain Open Space. Crossing over towards the west of the mountain down Miners Loop trail and down Lilac trail until reaching Black Mountain Ranch Park. From here runners will begin the Lusardi Loop trail.
