How does the T100 Triathlon World Tour series work?

The world’s best professional triathletes swim, cycle and run over nine events in nine different countries across the world between April and December.  

There are separate men’s and women’s competitions, with 20 triathletes taking part each.

The competitors must race in at least four of these events as well as the final in Qatar in December.

They can compete in more than four races if they choose, but only the sum of their four best point-scoring events, plus their score in the final, will count towards their overall total.

The male and female world champions are those with the highest totals after the final race.

Who is competing in the T100 Triathlon World Tour?

The roster of competing triathletes is made up of 20 men and 20 women.

The top 10 of the 2024 T100 Triathlon World Tour receive an automatic invite, as well as six more contracted triathletes from the PTO World Rankings.

The final four triathletes are ‘Hot Shots’ from the wider world of Triathlon.

Wildcard athletes can also compete for a chance at a 2026 contract.
