107 mi, 4 MB, 7500 ft; Mt Diablo South Gate,Mt Diablo Summit

Meet at 9am at Sycamore Valley Park & Ride lot. We'll canvas Diablo and then go far out and around the desolate valleys on some of my favorite East bay backroads, including a short stout climb, ridiculous descent, long-closed abandoned mining road, and oak canyon with vistas of the Diablo ridge. After a delicious taco lunch in the busted boomtown of Byron, lodge your best fight against the ferocious, undying headwinds on Altamont Pass for a chance of finishing the ride. Water available throughout. Start location: 1000 Sycamore Valley Rd, Danville, CA 94526 [Route/Map]
