Do cycling races and organized bicycle rides require prior authorization?

Correct answer: Yes.

Any competitive sporting event on public roads requires prior authorization, regardless of the number of participants. An organized bicycle ride, with more than 50 cyclists setting off together without competing, also requires it. A group of 50 or fewer is not an organized ride and follows the general traffic rules. Whether it takes place on a public holiday or a working day makes no difference.
