I actually met a couple of guys on the Scottish CX organising committee. They were busy with the event yesterday, but I've got email addresses.
The course didn't have much up and down, just a couple of dips, and they could use the concrete velodrome in the park, which was a great feature of the course. Not sure many places would be happy at the 'road' of mud created on the grass, but there must surely be potential in Edinburgh. Needs to be somewhere with good access and parking (and preferably some toilet facilities, and hose access to wash off bikes).
I'm going to raise it with the contacts I've now got... Edinburgh CX 2011 must surely be possible. There were a lot of ERC riders at Dundee (around 150 riders over the 4 races?).
