When entering a race which offers a £2 discount for ‘affiliated’ runners it’s always worth checking what licence or permit it is using. If it has a TRA or ARC permit then any club member should be eligible by virtue of the fact that RFRC is affiliated to both ARC and EA. However if it has a UKA (RunBritain) licence then you can only claim the discount if you are an EA registered (competitive) member of the club. Most big city races are licenced by UKA.
