Women In IRONMAN: A Timeline Of Milestones

Since the beginning, women have played important roles in the development, growth, and culture of IRONMAN triathlon. Unusually for a sport of its era, IRONMAN placed women on equal ground with the same distances, rules, and conditions as the men. Many of IRONMAN's most iconic moments have been delivered by female athletes, from Julie Moss's famous crawl in 1982 to record-breaking champions, coaches, and pioneers who mentor the next generation. Below is a timeline of the women of IRONMAN.

The Early Years (1977 To 1985)

1977-78 John and Judy Collins conceived the original "Hawaiian IRONMAN Triathlon," combining the island's three toughest endurance races into one, which led to the modern IRONMAN.

1979 Championship cyclist Lyn Lemaire competes in only the second year of IRONMAN and is crowned the first female champion, placing fifth of 15 starters. Inducted into the IRONMAN Hall of Fame in 2003.

1980 IRONMAN draws 106 men and two women. Robin Beck wins the women's division in 11:21:24 and places 12th overall.

1981 Valerie Silk takes over as race director and moves the triathlon from Waikiki to the lava fields of Kona, helping participation grow from 326 athletes to over 1,400.

1982 Julie Moss, a California college student, makes a heroic struggle to the finish, aired on ABC's Wide World of Sports. Passed near the line by Kathleen McCartney, who won the title, Moss crawls across the finish and the mantra "Anything Is Possible" is born.

1983 Sylviane Puntous of Canada becomes the first international woman to win in Kona, setting a women's course record of 10:43:36.
