A number of non-WTC full distance triathlons have been held since the mid-1990s. The limited number of WTC-sanctioned events, and the limited number of entries available per race, have combined with a growth in the sport that has created demand for these non-trademarked events. Many of them share the 2.4-mile (3.9 km), 112-mile (180 km), 26.2-mile (42.2 km) format with the Ironman triathlon. Originally, many used the Ironman name. Due to aggressive trademark protection, most of these races no longer use the word "Ironman".
