Earn Points for Your Club
Representing your club with your training buddies is one of the highlights of the Triathlon National Series. Any member of a club, who meets the criteria for competing in the Triathlon National Series is included in the Club Triathlon National Series.
There are three categories: Male, Female and Mixed. Six athletes make up the total points for each series. The top six male Triathlon National Series athletes of a club make up the total points for the Male Club Series. The top six female Triathlon National Series athletes of a club make up the total points for the Female Club Series. A mix of three female and three male Triathlon National Series athletes from a club make up the total points for the Mixed Club Series.

How are Points Allocated?
The Triathlon National Series employs a “30th percentile” points system with male and female Triathlon Ireland members ranked separately.
Here’s how it works: The triathlete who is at the 30th percentile of all TI members that finish a race (say 60th out of 200) will be allocated 100 points. The scores for all other times are calculated by reference to the 30th percentile.
For all the details on how the series works, see our Triathlon National Series page.
