Who knew? According to this recent study [
http://www.outdoorindustry.org/images/researchfile...] surveying outdoor sports, AR is growing really fast. See page 44 in the pdf for key stats & particulars.
Lots of interesting stuff in there. They don't show trail running as growing that quickly, but my perception is that trail running is a booming sport right now.
I need to look at the methodology a bit more. Note that "Orienteering" wasn't even a category they reported on.
I wonder if the fact that "adventure racing" is a nebulous term and could mean Muddy Buddy to one person, or the AR World Championship to another, is one reason for the statistics? The word "adventure" can mean so many different things. For that matter, orienteering and even geo-caching may have been grouped in with these stats? Is geo-caching still growing in the US the way it was a few years ago?
