You need to get there early and try to walk the course with someone who has run before.
Heres some pointers:
/\ ___________ /\ two cones 18+feet apart this is a gate you have to go through them
>/\ a cone on its side next to an upright cone means go around. These are directional cones if you go the wrong way around a cone with a pointer you are off course. you will see these in sloloms.
>>>>>>>>>> you may see a number of cones on there sides basicly making a wall. That is exactly what they are.
Things will make sence when you walk the course.
Good luck
