Fishy,
Where in S. Fla are you?

In the northern part of Dade (Miami Lakes) there is the Rosewood Criterium series.
It is a series of "training" races put on by the Miami Masters club. Here's a link... Miami Masters

There are also some groups that are FAST around Broward county, where you can get some pretty good "race" style training. Some of theme are no place for a new rider. Some are OK.
PM me if you want more info about some of the rides in Broward.
