IF IT’S THURSDAY IN KONA, IT’S THE UNDERPANTS RUN! (But Tuesday this year in 2022)

We are back and live, in person Tuesday October 4th, 2022. Going a little old school with just one day of pre-sign up on Monday October 3, 9am to 6pm, at the IRONMAN expo in Hale Halawai or just show up race morning early and donate and/or get some raffle tickets and then start running around town in you underpants!

With 2 days of racing and one of those days taking place on our traditional Thursday we have moved UPR two days
earlier, if you are on island come join us live.

Check out the “Event Info” page on the site for all the details but here are the basics:
We are keeping the tradition rolling and into its 24th year! It is only a $25 donation and with that you get your choice of a t-shirt from Greenlayer, socks from Beaker Concepts or underpants from Wood Underwear. As well with every donation you also receive a roll of UPR branded K-tape from Medline. We have raffle prizes from our partners including shoes from Hoka, GPS watches from Garmin and Betty Bucks from Betty Designs.

The run conceived of in 1998 by Chris Danahy, Tim Morris, and Paul Huddle as a protest against wearing Speedos in inappropriate places (stores, restaurants, etc.) has morphed into an IRONMAN pre-event ice breaker and local fund raiser that has become an integral part of the IRONMAN World Championship event week. Supported by the McMichael family (owners of Pacific Vibrations), Garmin, Hoka, Green Layer, Medline, Betty Designs, Wood Underwear, Big Island Running Co and, Multisports.com, the event continues to grow with the mission of having a little fun while giving back to this great local community.

Over the past 23 years we have raised over $340,000 for local charities through donations given towards Underpants branded T-shirts, underpants, hats/visors and socks as well raffle prizes from our partners.
