Brutally hot March day (by NorCal standards 78° is brutally hot, at least in March; yes we are soft). Trailran up from Jack London State Park. Thankfully large sections of the climb are in the shade so just kept eking along. But at about 1650' a steep section broke me and from there started alternating walk/run up to the Park Highpoint at the edge of a fence. Stepped (gingerly) over a tangle of barbed wire and followed a path across the meadow (mostly used by cattle) that led to the left past the towers and then linked up with tractor road to the obvious height-of-land. Jump over an electric cattle fence and look for a large cairn at the summit. Ran past a couple of hikers headed up to the highpoint as well, would be awesome if they join peakery someday.
