A mainstay in the history of the Ironman, the Ironman Lottery began in 1983 thanks to the vision of one of Ironman's founders, John Collins, as a way to provide athletes of all abilities the opportunity to qualify for the world's most challenging one-day endurance event. The 2010 Ironman Lottery Program officially opened on Wednesday, October 1 and will close on Saturday, February 28, 2010 with all winning entries being announced on Wednesday, April 15, 2010.
