no, I had done four miles the previous day, then six today. I figured my butt needed time to break in, since I have not been riding for several years. I started back about 3 weeks ago with a new folding bike. I ride for 20-45 minutes during my lunch break every day, and if I don't get a chance to I stop at the park on the way home and ride. At work, I ride lots of hills, there's no flat places. At the park it's all flat. But I stay in the saddle the whole time, it was just getting so uncomfortable from the midpoint of the ride today that I was shifting around, that's when I noticed that the pain was worse when I took pressure off the saddle.
thanks
