You know it’s Ironman World Championships race week on the Big Island when you see hundreds of triathletes running the streets of Kona in nothing but their skivvies. In its 19th running, the Kona Underpants Run took place on Thursday, Oct. 6, and judging from this year’s photos there were plenty of colorful and cleverly themed undies to be seen. The run is much more than just a thrilling 1.5-mile jaunt in one’s underwear, though, over the years it has benefitted local organizations, and uses the proceeds from the event to give back to the community. Plus, it’s a fun way to blow off some pre-race jitters.
The Ironman World Championships will take place on Saturday, Oct. 8.
