KAILUA-KONA, HAWAII, OCT. 6 -- Mark Allen won his second straight Ironman Triathlon World Championship here today, his 20th consecutive victory in triathlon competition.

Allen's time was 8 hours 28 minutes and 16 seconds, well off the record he set last year of 8:09:15. "It was a lot harder this year," he said.

Scott Tinley, the 1982 and 1985 winner, was second in 8:37:40. Following Tinley were Pauli Kiuru of Finland in 8:39:24, Rob Barel of the Netherlands in 8:45:47 and Greg Welch of Australia in 8:46:06.

Erin Baker won the women's title in the time of 9:13:42, good for 12th place overall. She also was well off the record of 9:00:56 set last year by Paula Newby-Fraser, who was second this year in 9:20:01.

Allen held less than a minute's lead over Rob Mackle of Bloomington, Ind., and Wolfgang Dittrich of Neuss, Germany, after the swimming and bicycle phases of the competition.

Dittrich was the first to finish the 2.4-mile ocean swim, while Mackle was second. Allen was ninth after the swim phase.

Dittrich swam the 2.4-mile course in Kailua Bay in 49 minutes and 5 seconds. He also was first in the swimming competition last year. Mackle was one second behind Dittrich after the first event.

Following the swim from the pier in this picturesque community on the island of Hawaii's Kona Coast, the 1,380 competitors started the 112-mile bicycle ride through barren lava fields and rolling ranchlands to the village of Hawi at the northeast tip of the island.

The bicycle phase ended and the 26.2-mile run began at the Keauhou resort several miles south of here.

Most of the sport's top competitors were here, vying for $160,000 in prize money and performance bonuses.
