T100 Explained

Everything you need to know about the ultimate global triathlon tour for pros and participants

World Triathlon Logo

T100 is triathlon,


20 of the world’s best professional triathletes – women and men – battling over a season of 8 breakneck 100km races in iconic locations around the globe in a bid to be crowned the first-ever T100 World Champions.

The T100 Triathlon World Tour will be the official World Championship tour of long-distance triathlon, recognised by World Triathlon, the sport’s global governing body and organised by the PTO.

Why T100?

Named after our unique 100km format, T100 is the sport reimagined: a 2km open-water swim that dictates the field of play, followed by an 80km bike course across varying terrain before a blistering 18km run to the finish line and glory. It’s the perfect combination of redline speed, human endurance and race strategy where it’ll take awesome strength, tactical prowess and perfect execution to take the tape first.

The T100 Triathlon World Tour not only celebrates this 100km format but also enables age group athletes the unique opportunity to compete at the same iconic locations as the professionals – whether trying triathlon for the first time or looking to push your performance limits at this exciting new distance.

Pro Athletes

T100 is the domain of the world’s best triathletes with 20 men and 20 women competing in every race. The majority of the athletes are contracted – either selected based on their PTO World Ranking or awarded a ‘Hotshot’ contract, earned by their standing in the sport outside of their PTO World Ranking Position.

On top of that, there will be ‘Wildcard’ athletes at each event – chosen by exceptional recent performances, top athletes coming back from injury or maternity or Olympians stepping up in distance.
