How To Position Your Race Number
CTT Regulation 16 details how to mount your race number.
The body number needs to be clearly visible from behind when you are in tour normal riding position.
In National Championship events and some circuit based events, arm numbers are also used. Arm numbers are worn on your upper arm facing either forwards or to the side depending on the preference of the timekeeper. Where only one arm number is used, it is worn on the left arm.
For the National Road Bike Championship, April 2025, there will be two arm numbers, both to be worn on your upper arm, the right facing forwards and the left facing left so that it can be read from the roadside.

ranging from separate shorts/tops, skinsuits and tri-suits. Swimming type suits and running
vests are not allowed. To be allowed to start all clothing shall be clean and tidy.
