Its clear... the biggest kiting event entries pools are for long distance open format races.
All equipment allowed, minimum levels of experienced, pros vs amateurs.
# Australia - L2L 19km : 110k Kiters and could be more
http://www.redbull.com.au/cs/Satellite/en_AU/Video/Lighthouse-to-Leighton-021242943019620# Australia LOC "26km?" not sure how many kiters
# Germany/Denmark C2C 40km : 300 kiters
# France - Defi Kite Race 40km : 250 kiters and they will look to include more
I'm sure there are other example but searching google seems most french kiting events also include a distance race.
Now the question being; with the obvious popularity, why are there not more such races? And a formal class created locally or internationally to develop and promote such events.
