It is totally awesome that the opportunity to race every week, multiple times exists. Just monitor your recovery! If you are new to the sport, any amount of racing is going to help. However, if you are serious about performing well in one of these series', or at an ABA race on the weekend, make sure to monitor your effort levels throughout the season. A good rule of thumb is no more than 2 really hard efforts a week.
