Muscles always gave out first. It takes about a year of consistent riding before muscle memory starts to set in and you really get comfortable on the bike Surges were also a big factor. It took me about a year before I was comfortably riding in the pack and I was trying to do 2-3 group rides a week, which helped a lot. Even slower ones will help to give you pack experience.
