The Ironman triathlon was settled by a bar argument in Hawaii — Commander Collins challenged friends to combine the island's three toughest endurance races. From Mission Bay 1974 to Kona's lava fields, from Olympic gold in Sydney 2000 to Jan Frodeno's world records, triathlon tests the limits of human endurance. This quiz covers every distance from Sprint to 140.6, the Ironman's Hawaiian origins, Olympic history, equipment, nutrition, and the sport's greatest champions.
Each round presents 10 randomized questions from a pool of 50, with four multiple-choice options and instant feedback after every answer. Your final score comes with a performance tier and shareable results.
You'll explore the founding of the Ironman in 1978 Hawaii, every race distance from Sprint to Full Ironman, why Gordon Haller won the first ever Ironman, legends like Mark Allen, Dave Scott, Paula Newby-Fraser, Jan Frodeno, Daniela Ryf, and Kristian Blummenfelt, the T1/T2 transitions, drafting rules, wetsuit regulations, the Brownlee brothers' Olympic dominance, and mixed relay at Tokyo 2020.
The Ironman World Championship is held annually in Kailua-Kona on the Big Island of Hawaii. The event moved there from Oahu in 1981 and features the iconic lava fields of the Kona coast. In 2022 and 2023 a second championship was added in Nice, France, to accommodate growing demand.
A full Ironman triathlon consists of a 3.86 km (2.4 mile) swim, a 180.25 km (112 mile) bike ride, and a full 42.195 km (26.2 mile) marathon run — totaling 140.6 miles (226.3 km). Competitors must finish within a 17-hour cutoff time.
Gordon Haller won the first Ironman Triathlon in 1978 on the island of Oahu, Hawaii, in a time of 11 hours, 46 minutes, and 58 seconds. Fifteen men started the race; twelve finished. Haller was a US Navy communications specialist and a multi-sport athlete.
