They always run a "red" course and a "corporate" course for those that are skeered of the red trails.
The start/finish is down the dirt road that's to the right when you're entering the park (past the dog park).
The red course is everything. The corporate course is the east side of LHP (no fingers, Rollercoaster, Beast, MOE, etc.) and is all intermediate trails.
It's a great race. You should check it out.
