I think most events like those have discount arrangements for competitors, like you say the NW200, they have always had them and we got them for the UGP as well.

There used to be discounts for the T.T for entrants as well, don't know if they are still available.

The difference with the Stena sporting rates are that they are available at any time all year round for anyone who is a member of a sporting club that is affiliated to the scheme and that members can travel for any purpose paying just the discounted cost of the vehicle with passengers, any friends or family, max five to a vehicle or a pillion passenger free.
