I seem to remember that bicycles were more comfortable when I was younger & cycle shorts don't seem to help either!!
I've been out for quite a few training rides & have also done a fair amount of 'spin' classes down the gym (Yes I do belong to one!). Apart from obvious places; I ache like mad. My right knee is particularly sore, however it's not stopping me; slowing me perhaps but not stopping me. The only up side is I am sleeping a lot better.
