Tyr Sport, Inc. is an American manufacturer of recreational and competitive swimwear, swim caps and goggles. It was co-founded in 1985 by Olympic medalist and former USA Swimming Co-Captain Steve Furniss. Tyr is based in Huntington Beach, California. Contrary to popular belief, its name is not an acronym. Rather, the company is named after Tyr (pronounced like "tier"), the Norse god of victory. The company makes products for swimming, diving, water polo, and triathlon. Tyr Sport is a subsidiary of Swimwear Anywhere, the second-largest swimwear manufacturer in the United States. Its chief competitors for market share are Speedo, Arena (swimwear), Blueseventy and Nike.
The Ironman World Championship has been held annually in Hawaii since 1978, with an additional race in 1982. It is owned and organised by the World Triathlon Corporation. It is the annual culmination of a series of Ironman triathlon qualification races held throughout the world.
