My mostly-annual Fall color tour of the Mill Creek valley. It was a wonderful day, sunny, low 70s, and light SW winds. Started in Alma and rode Old K-10, the rolling Skyline Mill Creek Scenic Drive, past Volland to Alta Vista. Stayed on the big ring all the way to Volland. At Alta Vista I turned back east on the relatively flatter K-4 with a rear quarter tailwind. Finally got onto K-99, the Native Stone Scenic Byway, northbound back into Alma. Made excellent time and beat the sunset back to Alma. We are at or near peak Fall color on a good year for it, and this route never disappoints. Note that my hard-shell old HRM is apparently also not a perpetual motion machine and may have a dead battery, so there's no heart rate data. I still haven't replaced the Orca's cranks, either, so the power data is bogus. A glorious day for riding, but not so much for data collection! Clinched my all-time best season of climbing and second-best all-time distance, all done is a lot less overall time than previously. Must be the new bike (not the old engine). Wore the Rapha Canyon-SRAM jersey and PI shorts. The Rapha's definitely a spring/fall jersey and was almost too warm for today's mild weather.
