From the correspondence....
The IRONMAN TriClub program is a great new way for clubs from all over the world to enter a regional and finally global championship. Yes, your club could be the next IRONMAN World Champion! Each club will be assigned to a division based on its size. Athletes belonging to your club collect points by racing at IRONMANR and IRONMANR70.3R events.
The top clubs in each division in Europe will receive an invitation to compete in the inaugural IRONMAN Europe Club Championship to be held in fall. The best club by points globally will also receive the title of IRONMAN TriClub World Champion.
