I'm not even sure of the convention of when you're allowed to look at your map. When I get handed a map with controls marked on it I'm generally ushered quickly to the start area and go straight away, one time I tried to look at my map as I was walking to the start area and was reprimanded by another orienteer who told me you're not allowed to look at it before you punch into the start control. For maps I've had to mark myself I've sometimes tried to have a sneaky look around me and orient my map before I leave the marking table... so I don't feel so embarrassed at the start 'cause I can move off quicker.
I just feel so dumb punching into the start control then standing there for 10 minutes turning my map every which way, looking all around me, choosing a route and then finally setting off. No one else does this.

So... am I really not allowed to look at my map before starting? And, how can I get my bearings more quickly so I can start running the course straight away?
