Long day of miscellaneous Marin County peak bagging: #1 Barnabe Mountain via Bill's Trail. #2 Big Rock Ridge from Lucas Canyon Road. #3 Little Peak via East Ridge use trail. #4 Burdell Mountain from Olompali State Park. Lots of gently graded trails so it was easy to mix in some trail running. Totals: ~24 mi, 4800 ft gain.
