I use a Cateye V3 (speed, cadence, HR). I'm pretty sure we're allowed to use them, I've not heard otherwise.
Not a great idea to have anything which may distract you while riding, but ok if you tape over any readout/screen and look at stats when the session is over.

An excellent, fun, safe first day.
