Ok, I decided to start riding last summer after 20+ years, so I went to a LBS got fitted for a bike and started riding. I did several rides of 30-40 miles last summer and had no problems, however on the couple rides I have done this year and while on the trainer I am completely numb within 30 minutes. I plan on going to the LBS to see if my riding position changed over the winter, but does anyone have any other suggestions I might try?
