69 miles and 10,000 feet of vert. That's what enticed me to the Dawg Size Increaser. I've been doing longer routes on my SuperSomething gravel bike and feeling pretty capable of accomplishing some hefty mileage, but most of it is in my own backyard. The Dawg Size Increaser circumnavigates Mt. Diablo counterclockwise, so it's all new territory to me. Definitely worth blocking off a full Saturday and letting my inner dawg run free.

Known to locals as simply The Geysers, this remote road climbs up 3500 feet along Big Sulphur Creek up to Geyser Peak, the site of the largest geothermal power facility on the planet. At the base of the climb there's a sign that says ROUGH ROAD, and I thought, "That's a pretty good description for my SuperSomething – a 'rough road' bike." Outfitted with 700x50 tires, my XL SuperSomething is set up for off-road adventures, but it still feels fast and floats like a hovercraft over the broken and dilapidated road and gravel surfaces throughout rural Sonoma County.
