You might want to check and see if the organization you're running with has loaner helmets.

If not and you can't find someplace nearby to try SNELL SA rated helmets you could find a motorcycle place and try some motorcycle helmets for size. It might give you an idea of what size you are and what brands may fit better which you can order online.

Otherwise I would suggest you order 2 or 3 helmets and plan on returning the ones that don't fit. You don't want to be thinking about how uncomfortable your helmet is while trying to learn how to drive a track!

I like my HJC helmet- it's lightweight and comfortable at a very reasonable price.

Good luck, have fun!
