The M-Dot is the famous IRONMAN triathlon logo. It is similar to an oversized letter “M” with an accompanying dot on top, typically red. It is the trademark of the brand. The “M” represents the word “mile” or “man,” and the dot represents the athlete.
It appears on apparel, medals, and merchandise. It indicates that an athlete is a member of the global IRONMAN community. It is the mark of victory for runners who complete the full-distance 140.6-mile (226.3 km) or the half-distance 70.3-mile (113 km) event. For triathletes, M-Dot represents hard work, resilience, and unity that transcends language and nationality.
