Sweden's Tomas Gustafson skated to a world record in the men's 10,000-meter speed skating race and won his second gold medal of the Winter Olympics yesterday in Calgary as American Eric Flaim finished fourth for the third time.

Gustafson, who earlier captured a gold medal in the 5,000 meters, skated the 25 laps in 13 minutes 48.20 seconds to break Geir Karlstad's 13:48.51 set last December in the same Olympic Oval.

Karlstad fell with seven laps to go in yesterday's race and was eliminated from the competition.

"It's a tremendous feeling," Gustafson said. "With 16 laps to go, I felt good. But I know from experience that that feeling can change rapidly."

Gustafson, 28, was a gold medalist at 5,000 meters and silver medalist at 10,000 meters in the 1984 Games.

Austria's Michael Hadschieff, skating four pairs before Gustafson, took the silver medal in 13:56.11. The bronze went to Leo Visser of the Netherlands in 14:00.55.

Flaim, whose silver in Saturday's 1,500 meters was the first medal for a U.S. speed skater since Eric Heiden won five golds in 1980, tired in the final five laps and finished in 14:05.57, as Heiden's previous Olympic mark of 14:28.13 was easily eclipsed.

Karlstad, who also failed to win a medal in the 5,000 where he is the world record holder, said it was his first fall in a race since he was 11.

"All my chances are over. I'm empty," Karlstad said. "I was tired. The ice was perfect. It was me."

Cross Country Skiing:

The Soviet Union's women coasted to a 1-minute 41.9-second victory over Norway in the 20-kilometer freestyle relay in Canmore, Alberta.

The Soviet quartet had a winning time of 59 minutes 51.1 seconds over a course with a vertical climb of about 210 yards.

Finland was third, 2:08.3 back. Marjo Matikainen of Finland became a triple medal winner -- the first of the Games -- with the relay bronze. She won the women's 5K and was third in the 10K.

It was the Soviet Union's fourth gold in the five cross-country ski events held so far. The Soviets also have three silvers and two bronzes.

The United States placed eighth.

Ice Dancing:

The Soviet couple of Natalia Bestemianova and Andrei Bukin took the lead as expected after the compulsory portion of competition, which ends Tuesday.

Bestemianova and Bukin, world champions the last three years, earned the first-place votes of all nine judges for their performances in the three dances: the Kilian, the Paso Double and the Viennese Waltz.

Marina Klimova and Sergei Ponomarenko, also of the Soviet Union, were second. Canadians Tracy Wilson and Robert McCall were third, edging Soviets Natalia Annenko and Genrikh Sretenski.

American champions Suzanne Semanick of Bridgeville, Pa., and Scott Gregory of Skaneateles, N.Y., were sixth. In the Viennese Waltz, their blades collided and she fell.

Aerial Freestyle Skiing:

Melanie Palenik of Littleton, Colo., vaulted her way to the gold medal in the demonstration event in which skiers do acrobatic maneuvers off an upturned ramp.

The event was held at windswept Olympic Park. Wind gusts were blamed for an injury to Maria Quintana, 21, of Steamboat Springs, Colo. Quintana, who had been in first place, hit hard after failing to negotiate a twisting triple back somersault.

She was unconscious for a few minutes, but got up on her own and was taken to a nearby hospital. She was treated for a minor concussion.
