I wouldn't ride ten miles with out my padded shorts and cycling jerseys. They make all the difference with comfort and staying as dry as possible. The pros don't wear them for nothing, that's for sure. I just wish that I could find team jerseys in women's cuts. My husband bought me a US Postal Jersey (I love Lance), but as I've heard in other threads, they are really tight on the hips and have a tendency to ride up. Make sure you get a jersey and shorts specifically for women!! Good luck. I look forward to hearing about your race.
