Finally got my Trek 7.3FX yesterday and got to go for my first ride today (8 miles through hilly neighborhoods)! Now remember that this is the first bike ride I have been on in a long time (excluding my rides at the beach with rented bikes). Ladies--is it normal to feel like I sat on a brick?? LOL I did wear padded bike shorts and my seat is a "women's specific" seat that came with my bike. I have heard women talk about needing to get an "iron crotch" when new to riding. Will this go away? I know I am going to be hurting tomorrow morning!
