Ride from the parking lot on Carmel Mountain Rd over to John's house, taking the normal route. It was really cold, with frost on the ground, and my hands were particularly cold. When I got to his house, we met up and rode to the top of Pomerado Rd, then rode down to get onto Kearny Villa Rd and Ruffin Rd, taking it over to Aero Dr. We rode up to Santo Rd, taking a left there and riding up to Tierrasanta Blvd. There is a steep section on Aero Dr that slowed me down. We turned left on Colina Dorada Dr, which has a climb of about a mile, with a steep section of about a quarter of a mile that was a trial. Over to Calle de Vida, riding it to Rueda Dr and taking a right there and using it to get over to Clairemont Mesa Blvd. We took it back to Ruffin Rd and from there retraced the route back to John's house. I stopped very briefly and then headed back to where I had parked the car. It was a decent ride, not super fast but a good steady pace.
