Corey Foulk, 49, an environmental architect from Kailua-Kona, is an 11-time Ultraman finisher who has completed 40-plus Ironmans, 50-plus marathons, and 50-plus ultra marathons. Plus he's done several since acquiring an artificial hip three years ago.

Peter Kotland returned to Ultraman 11 years after running a 5:33:57 double marathon to win the 1997 event.

The three-day stage race triathlon starts at 6:30 the Friday after Thanksgiving with a 10k swim from Kailua Pier to Keauhou Bay.
