This sounds doable. 2000 ft in a metric sounds like "rolling with a few big hills." Our local club has the following rankings:

Flat
Rolling
Moderately Hilly--I can do these, but it slows my pace considerably
Hilly or "billy goat"--DH goes to these alone!
(with the possibility of "a few big hills")

I pulled up the course map and it appears to start at the "top", go downhill, then flat to rolling with a big hill at the end. Personally, I would conserve and be ready for end. Maybe even going out for a training ride on the end of the course, if possible.
