No. There are a number of local races and travel races. You should just come to whichever you want. If you don’t want to do any competition but still come to all the trainings that is more than ok!
The travel races are in cool places, and a great way to bond with the team. It is a great way to have a fun weekend, even if you don’t want to raise the competitive level. That being said, if you are trying to race at a higher level, coming to the races is the best option.
