I just started racing this year, so I am in cat 5. My first event (3 stages) I finished 9th of 20 (and that includes a horrible TT which counted for the most points) and my next event, I finished 4th out of 20 and maybe could have done better if I just attacked about 10 seconds sooner. I feel I am a really strong rider and I go to the past pace group rides where 20 people show up and end up being in the group of 2-5 people that everyone is trying to hold on to and fail. Early this year (before I started racing) rode with a few cat 3 guys and on our group rides, we would always hammer/ race up the climbs and when I started winning on these sprints, they were surprised to learn that I didn't race and said that I would do great if I ever picked it up.
That being said, I am wondering, how exactly do you move up to cat 4?
