PTO World Rankings Protocol


The World Ranking System of The Professional Triathletes Organisation is designed to identify and rank the world’s greatest triathletes who participate in professional half-distance and full distance triathlons. The PTO World Ranking System measures consistent excellence and will be used to determine the automatic qualifying places for The Collins Cup.

Under the rules of The Collins Cup, the top four ranked men and women athletes from each of the USA, Europe and The Internationals will automatically qualify for a spot on their respective team. The PTO World Ranking System has been formulated so as not to favour any series of races or races in any geographical area, but to measure talent and achievement based on the results of an athlete no matter where and when they choose to race.

Eligibility of Professionals

Any athlete who holds a professional license from, or is considered in the elite/professional category by, any race organiser or governing body and is a PTO Member in good standing will be included in the PTO World Ranking System.

Eligible Races

Any race that has a professional prize purse that is equal for men and women and is of a length greater than Olympic distance will be considered eligible for an athlete to earn PTO World Ranking points (an “Eligible Race”). This will include all Challenge-Family, IRONMAN® and ITU sanctioned races longer than Olympic distance, as well as independent races with minimum professional prize purses. All Eligible Races have equal value in calculating points towards a PTO World Ranking. An athlete’s points will depend on their time and not on their place in a race or the strength of the field. Unless otherwise noted at least six months ahead of time, no specific race is given any special treatment or weight.

Ideal Time Measurement

Based on proprietary analysis of historical data developed by and exclusively licensed from, the PTO has ranked each Eligible Race and determined the theoretical ideal time (the “Ideal Time”) that the top ranked athlete would achieve on the course. While each Eligible Race will have an Ideal Time, a proprietary algorithm adjustment mechanism will be applied so that the Ideal Time will be modified based on the course conditions on the day of the event (the “Adjusted Ideal Time”).

For example, there may have been currents during the swim, or particularly difficult wind or heat. An athlete’s PTO World Ranking points will be based on measurement against the Adjusted Ideal Time. To the extent an Eligible Race is held on a new or modified course, the PTO will analyse the course elements and determine an Ideal Time for the race, and then apply the propriety algorithm adjustment mechanism based on course conditions on race day to determine the Adjusted Ideal Time.

World Ranking Points

If an athlete equals the Ideal Adjusted Time for any Eligible Race, they receive 100 points. To the extent they are faster than the Adjusted Ideal Time, they will be awarded an additional point or fraction thereof for each .15% by which they beat the Adjusted Ideal Time. To the extent they are slower than the Adjusted Ideal Time, they will lose an additional point or fraction thereof for every .15% by which they are slower.


Athletes will be ranked based on the aggregate number of World Ranking Points that have earned for their four best races over a 104-week period (approximately 24 months) preceding the date of calculation; provided, however, if a race falls outside the most recent 52-week period (approximately 12 months) preceding the date of calculation, the points earned for such a race will be reduced by 10%. In addition, each athlete will be given a 5% bonus of points for their best full distance race that is included in their four best races. Only one race from outside the most recent 12-month period preceding the date of calculation may be used for an athlete’s ranking.

Maternity Policy And Injury Leave

The PTO World Rankings protocol has provisions that relate to athletes that go on maternity leave or injury leave.


The PTO World Ranking System may be amended or modified at any time by the determination of the non-athlete members of the PTO Board.
