Incredible 24 hour adventure with Andrea Achilli and David Wilcox. The middle section—Fish Rock, Elkhorn, Rockpile—was 75 miles and took us 9.5 hours. No services in that stretch, so each of us made do with two water bottles. Much of the dirt section of Rockpile was hiking—the terrain was just too steep to cycle, at least in our depleted conditions. We saw a large group of wild boar (plus a lone adult), two mountain lions, a pack of five coyotes, an owl, and deer too numerous to count.

Note the altitude anomaly around Healdsburg. Still, other than the stretch around Healdsburg, the data is correct and untouched.
