At the CTT (Cycling Time Trials) National Council AGM on Sunday 5 December 2021, several changes were made to CTT’s regulations. In particular, two important regulations were passed and are implemented with immediate effect:

ALL riders must have a working front light attached to their machine. (Regulation 14(j))

ALL riders now must wear a helmet.  (Previously this requirement was only mandatory for under 18s).  (Regulation 15)

The full regulations can be viewed on the CTT website.
