KONA (HawaiiNewsNow) - How would like to run for a mile down a busy street in Kona in your underwear? Nearly 1,000 people did just that Thursday for a good cause.
The athletes stripped down to their skivvies for a charity run on the Big Island, it's an annual tradition before Saturday's Ironman race.
The 14th annual Underpants Run was started after some triathletes noticed that some of the visitors in Kona during Ironman would wear Speedos into restaurants and into grocery stores.
The fun-run raises money for nonprofit organizations, including Special Olympics.
Prior to the run, participants say an oath in which they pledge NOT to wear their Speedos to stores and restaurants then the runners take off to Kailua Pier for a quick round of calisthenics and then continued along Alii Drive.
Eight-time world champion Paula Newby-Fraser helps organize the run. 18-hundred swimmers, runners and bikers will take part in the race on Saturday.
