We used to ride from Northridge CA to Malibu and back on Stingrays when we were kids. It must have taken 14 hours. I remember my rear hub (Bendix grease-drum) would sizzle and smoke after coming down the Santa Monica mountains. I couldn't imagine riding 60 miles on a 20" single-speed with no food or water on a so-cal summer day, but I did it.
