Saturday, October 12: 
Ironman Triathlon World Championship.  The top 1,800 triathletes from around the world (50 countries and all 50 States) converge on Kona for this Super Bowl of triathlon events, featuring a 2.4-mile ocean swim off Kailua Pier, a 112-mile bike course to Hawi and a 26.2-mile run. The first racers swim at 6:30 a.m. The top finishers complete the event around 3:30 p.m.; the last official finisher is at midnight. Spectators may enjoy the race anywhere along the course (but note that roads around the area are closed), but being right downtown in Kailua Village is the best way to see the action.
