From the door at East Peak on Mt Tamalpais to the door at the top of the summit visitor's center at Mt Diablo... 55 miles and roughly 10,000 ft of climbing (the majority done in the back 20 miles), The Tamiablo is a challenge more sneaky than the numbers indicate.

We followed the described route, with only two modifications on the Briones to Mt Diablo trail: Traveling on the parallel Ridge Top/Coastanoan Trail into Borges Ranch for water, and later dropping onto Stage Road Trail via Buckeye Ravine Trail.

The trip was unsupported, with water filled at drinking fountains along the way (at approx. miles 4,13,17, 32, 41, 47, and 53), and from a stream at the Briones Reservoir.
