Solo ride on a Wednesday from home, before going to work. I left a little after 6:00, and it was dark at the start, so I had my lights on. Headed through the neighborhood to RB Rd and over to Camino del Sur. A little ways on this road, and I saw a couple of other cyclists ahead. I tried but couldn't catch them, as they were really motoring. I closed the gap on the little hill before San Dieguito Rd, but that's where they turned, so I lost them. Stayed on Camino del Sur until the 56 bike trail, heading west. I was able to keep my pace above 20 mph on the little uphill stretch between the two slight downhills. Down to El Camino Real, where I felt like I had a decent ride up to Del Mar Heights Rd. Down and around to San Dieguito Rd, heading back home via the Three Witches climb. Here, I was able to keep my pace above 10 mph, mostly above 11 mph. I retraced my outgoing route on the way back, not super strong or pushing the pace. Finished in under 2 hrs.
Avg speed = 17.5 mph. Total mileage = 33.9 mi
