Quick background: Purchased my Felt Z100 in July, have ridden about 700 miles on it since over about 25 rides. I completed my first century ride this past weekend. I plan on getting stronger through the winter using an indoor bike trainer and Trainer Road.

My question is, how long (if ever) does the pain of sitting down go away. I usually feel fine for the first 20 miles or so, afterward I get increasingly uncomfortable. I do have decent bib shorts which I wear.

Part of it is my bike fit, which I know because I develop a knee pain after extended periods of time. I'm also way heavier than I should be, I usually am about 185-190 but am currently around 215. I know getting down to my normal weight will likely solve a lot of it. I'm also getting the bike refit this week which I hope will alleviate some of the issues.

I started my indoor training and the soreness just becomes unbearable after 45 min or so. Will this just go away with more frequent riding (more than the 1-2 rides a week I have been doing)? For you veteran cyclists, does it ever go away?
