How many ironman marks are there?

There are three levels of Ironman marks in traditional Ironman triathlons: Ironman, Ironman 70.3, and Ironman 140.6. Each level represents a different distance of the race, with Ironman being the full-distance triathlon, Ironman 70.3 being a half-distance, and Ironman 140.6 being the full-distance branded specifically by Ironman.
