usually you can find a link via the BE fixture list, but eventriders.com has course descriptions on it, so look there too.
It's a pretty straightforward course, no big hills, some portable fences (like a jump with a water trough in it complete with floating ducks)
Dressage is in a corner of the same field as everything else, showjumping the opposite corner, everything is very near to the box park etc and easy access off the main road.
I looked for info re that new event but it isn't up yet.
