Yesterday after my morning upper body workout, I went for a ride with my hybrid e-bike. This has fairly fat tires (38 mm) so it does well off pavement. I took a back road with lots of gravel shoulders (Dougherty Ave) to Palm Ave to the Coyote Valley Open Space preserve, then did some more off-road riding there. The high was 95 F (35 C) but it was still reasonably cool at the time of my ride so it was enjoyable.
