A staple of race week at the VinFast IRONMAN World Championship in Kona, Hawai`i, over 1,500 participants took to Ali`i Dr. for the UnderPants Run presented by The IRONMAN Foundation.
Conceived in 1998 by Chris Danahy, Tim Morris, and Paul Huddle as a protest against wearing Speedos in inappropriate places, the event has morphed into an IRONMAN pre-race icebreaker and raised over $52,000 in non-profit giveback for the race communities.
