Lili'uokalani races in Kailua-Kona

Billed as the world's largest long-distance canoe race, the 39th Queen Lili'uokalani Race opens three days of competition tomorrow in Kailua-Kona.

More than 3,000 outrigger canoe paddlers from Hawaii, the mainland and around the world are expected to vie in six-man, 12-man, OC-1 and OC-2 divisions as well as stand-up paddleboards.

New this year is Monday's Ali'i Challenge, a 17.5-mile mixed race with six women and six men. The all-woman crews will paddle from Kailua Pier with the men's crews making open-water changes halfway through the course. The finish is at the Kona Village beach.
