After two months of smoky conditions in the Bay Area there was finally got a break in the weather and I decided to give this a go. I followed the route set by Franz van der Groen which starts at the East Peak summit door on Mt Tam and ends at the summit door on Mt Diablo.
The trip was unsupported, with water filled at fountains at miles 2, 14, 18, 32, 39, 45 and 51. Also a refill from the stream at the Briones Reservoir at mile 27.
This is the only run I know of where you can see the finish from the start!
