There is some information about practice maps on the event's Locator Maps page. I don't think there will be a model course, but a practice map for Carter Caves should be in the packets at check in. Doesn't look like the practice area is very big.
There is a very small practice / warm up area at Carter Caves. you can print the map from the locator maps page. Also, a print will be in your packet, and there are a few copies on the front desk at Carter Caves lodge.
