Hi, MightyMitre ...the swollen thighs are not painful but believe it or not they do get hot to the touch and hard. I am not sure if it could be from the riding itself or not. It takes a day or two of not riding for the swelling to go down. I just went out and had my seat readjusted and I am still considering a new seat possibly with a nose that is more narrow. It really is a just more uncomfortable and annoying than anything else and I sure would like to think that I am not the only one to have such a strange problem. We recently did the Greenbriar Rails to trails in West Virginia and not only did my thighs swell, but I also developed a raised rash similar to hives on the top of my thighs....go figure it took two days to go away. Perhaps I am allergic to long bike rides, We did 80 miles one day and 35 the next. Anyway thanks for your response...
