International Triathlon Union Lots of info about ITU-races, including results and calendar. Also the ITU-rankings (interesting to see who can go to the
Olympics). Details about rules etc. You can also subscribe to the ITU newsletter and read back issues.
European Triathlon Union Official homepage for the ETU. Details of races and ranking. I personally think this site could be more attractive, but you get the necessary
content, like info on ETU rankings and races and links to many European national federations.
