Marianne Timmer hung up a time world record holder Christine Witty could not match and won the women's 1,000 meters Thursday, joining fellow Dutchman Gianni Romme as a double gold medalist in Nagano Olympic speed skating.

The 23-year-old Timmer proved her surprise 1,500-meter triumph was no fluke, setting a new Olympic record of 1 minute, 16.51 seconds at the M-Wave indoor oval while skating alone much of the 2-1/2 lap race.

''I'm really surprise to win two gold medals and this is what I'd never expected,'' Timmer said. ''It's really a good feeling and my dreams have come true.''

Witty added the silver to her 1,500-meter bronze by finishing 0.28 second behind as the United States continues to wait for its first Nagano Olympic speed skating gold.

The bronze went to 500-meter gold medalist Catriona LeMay Doan, who clocked 1:17.37 in winning her second Olympic medal.

Timmer, skating in the next-to-last group, trailed German racing partner Franziska Schenk by 0.36 second at the 200-meter point shortly before the German sprinter fell going into the next corner and tumbled out of contention.

Timmer skated alone for the rest of the race and shattered the 10-year-old Olympic record of 1:17.65 set by East German Christa Rothenburger at the 1988 Calgary Games.

''In the next lap (after Schenk fell), I saw her there in the corner but I didn't know what happened,'' Timmer said.

''She is a really good skater and the best thing is that she should have had a good race, too. It's nice to win when everybody skate well,'' Timmer added.

Schenk, the 500-meter bronze medalist in Lillehammer four years ago, was bidding to capture her first medal here following her fourth-place finish in the 500 meters last week.

Timmer had to wait for favorites Witty and Canadian Susan Auch, the 500-meter silver medalist, to complete their race in the final pairing of Thursday's competition.

Witty was leading Timmer by 0.08 second after the first 200 meters before the advantage turned into a deficit of 0.09 at 600 meters. The American favorite couldn't make up for the lost time in the final lap while Auch slumped to finish 18th.

Timmer's latest victory increased the Netherlands' medals count at Nagano to 11 -- five gold, four silver and two bronze -- all in speed skating.

In addition to Timmer's double, Ids Postma claimed the men's 1,000-meter gold while Romme triumphed in the men's 5,000 and 10,000 by churning out stunning world records.

Local favorite Tomomi Okazaki, the 500-meter bronze medal winner, finished seventh in 1:18.27 for the best performance among the four Japanese entries.

''I tried to bring the momentum I had by winning the medal into today's race. But it proved too much for me to do any better than my placing,'' Okazaki said.

Japanese national record holder Eriko Sammiya followed in eighth place 0.09 second behind. Shiho Kusunose ended up in 11th and Kyoko Shimazaki in 22nd, respectively. (Kyodo News)
