Solo ride from home after work on the short loop out to Pomerado/Twin Peaks and back. Felt okay, although I sensed that my heartrate was higher than normal. A little slower than I would have liked on the climb up Twin Peaks to I-15, but otherwise it was a good ride. Some cramping in my calves and feet after the ride but nothing painful.
Average speed = 17.8 mph. Total mileage = 12.6 mi.
