That ride sounds fun ! Glad you felt better once it was over. You'll get through the century. You strong like ox . I'm sure since you were with DH (and not me), you were flying, which probably contributed to the sniveling after mile 50. Pace yourself and you'll be fine.

I think your shorts are too big for you, hence the wedgy. You've lost more weight since you bought them. Time for a smaller size.

Still no new bike for me !
