The PTO World Rankings is a first-of-its-kind ranking technology to measure the world’s greatest non-drafting professional triathletes. It is a worldwide benchmark of consistent excellence in triathlon, and it is used to determine the automatic qualifying places for The Collins Cup and the payment of PTO Professional Annual bonuses.

The PTO World Rankings has a proprietary formula that does not favour any particular series of races or geographical area, but instead measures talent and achievement based on the results of an athlete no matter where and when they choose to race. 

The PTO, in association with TRiRating.com, has analysed each racecourse to determine the theoretical Ideal Time that the top ranked athlete would likely achieve. Using proprietary algorithms, this Ideal Time is then adjusted based on the conditions of the race day to determine the Adjusted Ideal Time (AIT). An athlete’s PTO World Ranking points (“World Ranking Points”) for his or her race will then be based on their race time set against the Adjusted Ideal Time. 

If an athlete equals the AIT for any eligible race, they receive 100 World Ranking Points. If an athlete is faster than the AIT, they are awarded an additional World Ranking Point or fraction of a point for each .15% by which they beat the AIT. If they are slower than the Adjusted Ideal Time, they will lose an additional World Ranking Points or fraction of a point for every .15% slower.

Until the completion of the Collins Cup on August 28, the PTO World Rankings shall be determined by averaging the World Ranking Points earned by an athlete from the highest two of (i) any races completed between December 1, 2020 and before August 9, 2021 and (ii) the average of the Athlete’s best three races for from December 1, 2018 and December 31, 2020.

After the Collins Cup, The PTO World Rankings shall be determined by the aggregate number of World Ranking Points an athlete has earned for their three best races for 2021, with the final rankings on December 31, 2021, determining the pay-out to PTO Professionals under the PTO Annual Bonus System.
