I just got back from a 35+ mile ride. It was GREAT. How great, you ask? Very!
I usually go out to ride with a rough plan. I'll choose a route based on wind direction, how I feel, how much time I have, how hot it is, and so on. Today, my plan was to go out QQ for 15-25 miles; depending on how I felt, I'd turn back at whatever point.
I turned back at about 13 miles (which is where the quieter road hits the busier road, and so it's a good place to turn back and stay on the quieter road). My feet weren't numb AT ALL, though in the past, they've started going numb at 8-10 miles. In addition to adjusting a cleat to be straighter and my seat, the bike fitter had given me a few stretching sorts of things to try on the bike, and they seemed to help a lot, but not as much as the cleat adjustment did.
I rode back most of the way, to the point where I cross a bike path, and then because I was feeling so good, and my feet weren't numb, I turned onto the bike path and rode a while more. When I turned back, I turned more because I was hungry (I stopped on the way back to get a sandwich because I hadn't taken one since I hadn't planned to ride so far) and tiring, and didn't want to get too far out and face a headwind coming home.
It's so much better to ride without numb feet! I can't believe I didn't get a bike fitting sooner!
Now I'm tired, but not sore or anything.
I loved my bike a lot before, but now it's even better!
