Some outdoor running paths (parks, etc in SoCal) have exercise stations along the way. Like chinning bars at one station, the next station might have a situp set up, dips bars, pushup bars (mounted to the ground or in cement), ladder bars, etc, etc, etc.. Even cement bench stations for one legged step-ups, ham stretches, etc.
Lot of Tri athletes do sand sprints, and at time up the sand dunes, at the beaches. Can usually workout all year round out here.
