Mount Diablo | 40 Miles (65 km) | ~4,000 Ft (1200 m)

A 40-mile ride and a first attempt to climb Mount Diablo (at approximately 3800 feet of elevation) on a hot day. At the base I think it was over 90 degrees (32 C). Beautiful route and scenery. I got a flat again. I am considering switching back to butyl tubes because I have not had any luck with the TPU ones I’ve been using. Got 4 flats in the last few months. Maybe switch to a different brand (using RideNow tubes now).
