Thank you Geoff. Appreciated.Give them a call and ask them directly, 0115 982 1212
I've rung the number given by [Nikon photographer] And a very nice lady suggested i e-mailed someone in a separate office. This i did last Monday and so far I have not received a reply. However the replies from Hugh and Jon above, imply that its ok to just go and photograph the white water events.It's a fair ride away from me, but if photograpy IS allowed, it could be good for action shots.
Grateful if you could update with any response you get.
Thank you.
