From a 25 mi, 1,500 ft hill and coast fitness ride several days ago. Still working off the Holidays. As an enticement to climb, the route strung together several favorite local descents.
First stop, a favorite overlook at the top of the ride. Thanks to our ongoing Santa Ana winds, my clearest view ever of Calavera volcano and its many trails. Most are closed to all bikes, and I'd need an MTB for most of the rest.

To the SSE, the scrub-covered San Elijo Hills, the highest points within 20 mi of home. The highest-looking summit with the 2 lone trees is Double Peak (1,645 ft), popular for its spectacular 360° views of a big chunk of southern SoCal and adjoining Mexico.
Down at the volcano, put in several flattish miles on one of the few bike-legal trails there. The sandy texture, erosion style, and whitish color identify the underlying rock as the Santiago Formation — a crumbly, easily eroded Eocene marine sandstone some 45 million years old.
Santiago Formation trails are typically rutted, off-camber hardpack slick with a thin veneer of loose sand. The steepest are way too scary for me, but the SL and its 38 mm tubeless gravel tires did just fine here at ~40 psi.
The trail turnaround at Lake Boulevard.
From there, non-stop back down to the coast with several fun descents along the way. North Ponto Beach near low tide.
This old guy on a gravel bike reminded me of me — about my age, and the only rider on the sand. In a land of a zillion fat-tire ebikes, still don't understand why beach riders are so rare here.
Followed him up the beach, wishing I were down there next to the waves but not in the mood for the careful bike rinse that would have to follow as soon as I got home.
Instead, decided to kill the hour till dinner in my favorite chair at the South Carlsbad State Beach Camp Store.
Nice view down to the beach from there. Always interesting to watch the small dying waves interact in the shallows — often in very counter-intuitive ways.
As usual on nice afternoons, the place was parked up with ebikes, many set up for hauling surfboards or kids.
This one belonged to a 60-something banker-type I chatted with briefly. Odd name for an ebike.
