The event will be based at The Black Rabbit pub on the banks of the River Arun, Mill Road, Arundel, West Sussex BN18 9PB.  Registration and the transition will be at this location.  Parking at the Black Rabbit Pub is limited so you’re advised to park in Mill Road and walk up to the pub or park in the main car park at Arundel opposite the Castle entrance. A bus shuttle will operate from here to ferry competitors to the pub. Other parking options may become available and we will notify competitors of these.   If you arrive in Arundel on Saturday afternoon the town is likely to be very busy, the easiest place to park is likely to be behind the museum by the entrance to the Castle (Mill Road, Arundel, BN18 9PA)
