Not racing, but I have done a few laps of the planned course. Expect the usual Gorrick style fun course. Lots of twisty singletrack, no big climbs but the course is rarely flat. I would say it will be a fairly tough course for the longer races, due to how twisty and undulating it is. Nothing too technical – my 11 year old daughter can ride all of it. The amount of singletrack might make passing difficult so as always a good start will be important. I have only done one ‘fast’ lap of the course and there wasn’t much opportunity to take a drink, so if you are doing more than 2 hours, make an conscious effort to eat and drink regularly.
Good luck and have fun!
