In 1979, Commander John Collins had postponed the race one day, then delayed the scheduled 7 a.m. start, afraid for athlete safety not only in the turbulent passage of the swim, but also that during the 112-mile bike segment a sudden squall might unseat a rider.

In 1979, sports photographer Peter Read Miller traveled to Hawai`i to document a race called the IRONMAN. His photos were published in Sports Illustrated and exposed the world to the sport.

We invited him back to Hawai’i for this past year’s World Championship to document the 40th anniversary.

During this week, we’re going share many of his photos and stories from 1979 and 2018.

Congratulations to our winners from this weekend’s IRONMAN 70.3 Geelong!
