This one-of-a-kind event, presented by the IRONMAN Foundation, is a fundraiser for the Hawaiian community. Your donation to participate will support The IRONMAN Foundation and its mission to create positive, tangible change in race communities through grant funding and volunteerism.

Since 2003, The IRONMAN Foundation, in partnership with The IRONMAN Group, has provided more than $60 million in charitable giveback to 10,000 organizations around the world.

Your $30 participation donation secures you an official spot on the Kona UPR start line, as well as a pair of Wood Underwear (official Underpants of the KUPR!). PLUS the opportunity to purchase official merchandise items (official KUPR BOCO trucker run hat). All items are available on a first come first served basis and until supplies sell out. Participants will also have the opportunity to acquire raffle tickets at the in-person packet pickup.

The Underpants Run (UPR) is a  1.5 – 2 mile (approximately) out and back fun-run on Alii Drive, starting and ending at the parking lot of the King Kamehameha’s Kona Beach Hotel. Plan for multiple stop-and-go moments while on the run course as spectators and participants alike enjoy photos, cheer stations and comradery.

• All ages, including children, are welcome to participate.
• Strollers are allowed.
• Well behaved pets on leash are allowed.
• Please no bikes or motorcycles while on the course (we will provide official lead vehicles for your safety).

• Plain and simple UNDERPANTS or any outfit of your creative choice.
• Women should have proper tops/covering. 
• No public nudity allowed!

Please remember, this is a family friendly event!
