After studying the 3D map in peakery, pieced together this, ah, unconventional Headlands trailrun loop. Steep, rough, overgrown paths with many patches of poison oak. Rodeo Valley Stables > Hawk Hill bunker > down a moderately treacherous, rarely-traveled path to Kirby Cove > up a direct offtrail path climbing Slacker Hill's south ridge to the summit, down an obscure path on Slacker's west ridge > back down the Coastal Trail. Rushed home to apply Technu but alas I think 'twas too late.
