Our ranking of the 15 best triathletes of all time, led by Paula Newby-Fraser, Mark Allen and Dave Scott, with Kona and Olympic titles.
Each profile lists the triathlete’s main distance, country, birth date, career span and the titles that matter, followed by what made them stand out. Ironman racers and Olympic distance specialists share one list, and men and women are ranked together. Below the ranking you will find the best name for each part of the sport, the records our triathletes hold and the athletes who just missed the cut.
How We Ranked the Triathletes
- World titles: wins at the Ironman World Championship in Kona and world titles over the Olympic distance carry the most weight.
- Olympic gold: triathlon has been an Olympic sport since 2000, and an individual gold counts heavily.
- Dominance: winning streaks, unbeaten runs and course records against the best fields of the time.
- Range and longevity: success over several distances and the number of years an athlete stayed at the top.
Comparing a two hour Olympic race with an eight hour Ironman is never exact, so we look at how far each athlete stood above the rest of their own field. Athletes before 2000 had no Olympic triathlon to win, and the Ironman World Championship moved between Kona, St. George and Nice in recent years. The order is our own judgment, not an official one.

Newby-Fraser won the Ironman World Championship in Kona eight times between 1986 and 1996, more than any other athlete, man or woman. That record earned her the name “The Queen of Kona”.
She was born in what was then Southern Rhodesia and grew up in South Africa, where she was a nationally ranked swimmer as a child. Her Kona course record stood for 17 years until Chrissie Wellington broke it in 2009. She won 24 Ironman races in all between 1986 and 2002.
#2 Mark Allen

- 🏛️ Hall of Fame: 1997 (Ironman Hall of Fame)
Allen lost at the Ironman World Championship six times, often to Dave Scott, before he finally won in 1989. That race against Scott, decided by less than a minute, became known as the “Ironwar”. He then won five in a row from 1989 to 1993 and a sixth in 1995 at age 37, the oldest winner at the time.
He was just as strong over shorter races and won the first ITU World Championships in Avignon in 1989. He went unbeaten in ten trips to the Nice International Championships and once won 21 races in a row over two seasons. Outside magazine named him the World’s Fittest Man in 1997, the same year he entered the Ironman Hall of Fame.

Scott was the first athlete to win the Ironman World Championship six times, between 1980 and 1987. At his first Ironman in 1980 he finished in 9:24:33, almost two hours faster than the previous winner. His approach is widely seen as the moment the Ironman turned from a test of survival into a real race.
His rivalry with Mark Allen peaked in 1989, when he lost by under a minute in the race now called the “Ironwar”. In 1994, at age 40, he came back to finish second, and at 42 he placed fifth with a 2:45 marathon. In 1993 he became the first athlete inducted into the Ironman Hall of Fame.

Her Kona course record from 2009 stood until Mirinda Carfrae lowered it in 2013. Her overall Ironman-distance record lasted 12 years until Daniela Ryf beat it in 2023.
