I'm 6'3 215'ish. You can move up to sport and it'll definitely be more of a challenge BUT if you're not on the podium in beginner, chances are you'll be toward the back of the sports class. This can be a deflater or a motivator. I'd say do it, talk to the race director and see if you can "try" a cat2 race. The big difference with the move was not only the difference in competitors, it was the distance of the races. One thing I noticed, there aren't many 200+lb's in our Sport class and even less in the Expert.
We are at a severe disadvantage which you can either use as an excuse or a motivator.
One thing on your size that I noticed. Nobody cares. You're a racer (just larger) so don't use it as an excuse for poorer performance or as a crutch. Just go out there and kick their butts!
