Sport climbing (the classic Lead discipline and the newcomer Bouldering) has a very good fan base in many Countries around the Alps (France, Italy, Austria, Slovenia, but also in the Czech Rep. and in Germany)...
there are also very good atletes from Belgium, GBR, Canada, US and even some Asian Countries (KOR above all, but also CHN, JPN and IRI)...
the Speed discipline, on the other hand, it's almost entirely dominated by RUS, UKR and POL, with very few exceptions...
as someone suggested, the international federation has a very good website, where you can find info, stats and videos of their main events throughout the year)...

the only problem is that they won't have the 3 disciplines at the Olympic Games in 2020, but a senseless "combined event", which doesn't even exist in sport climbing until now...
so, not the best way to promote this sport, I guess...
