I started out today to do a 71 mile ride with about 3800 ft of climbing. I didn't have much energy and my legs were a little sore, but often when this is the case, after about 15 minutes of riding or so, the energy kicks in and the legs loosen up. That didn't happen today. The energy never came. After 9.6 miles of riding and about 1000 ft of climbing, I decided to change my plans and attack the planned training ride another day. I couldn't, however, abandon my Saturday ride being longer than my other rides in the week, so I adjusted my route and decided to try for a relatively flat route that I could get some miles in with. This route is what resulted. I still didn't have energy and my average speed was quite low, but I got some miles in. And it turns out another 848 ft of climbing. Don't let anybody tell you Tucson is flat. It ain't!
