A Mostly Flat Route in Nor Cal, May 2018

Start point: 36°40’21N 121°15’08W elev 257m
U-turn point: 36°31’04N 121°08’15W elev 415m
Total ascension (2 ways): 316m (1,037′)


Our bikes, which had taken us over the rounded hills of England’s South Downs, up and down the plateaus of Cornwall, and through French forests and Florida swamps, were not quite up to the task of taking us over the steep hills of California’s mountain ranges, where mountain biking was born. So we set to building new bikes. Until then, we sought out the flattest routes we could find.

On a sunny, still day in May, we took scenic Highway 25 in Paicines, near Hollister, San Benito County, all the way to the entrance of Pinnacles National Monument. It was a 15 mile (8 km) ride one way, and was mostly flat except for a single section that accounted for most of the ascent, which was a bit of a challenge on a three speed.

Highway 25 is also known as Airline Highway. Sections of the road are so flat and so straight that we wondered if the road had once served as a landing strip, but some cursory online research offered another explanation. Steve Johnson, of the Road Pickle blog, explained that “before the advent of radio communications, airplane pilots used the highway as a visual aid.”

The road follows the San Andreas fault. It was a very surreal experience to be straddling two tectonic plates.

The many folded hills looked like arms nestling grazing cattle.

The scenery is so beautiful that the road is eligible for State Scenic Highway designation.

If you go, you won’t regret stopping at Eva Mae’s Café . Although they don’t allow dogs inside the café, they insisted on bringing a table outside for us. The hospitality and the food were both excellent.
