WHISTLER, British Columbia — A men's Olympic luger from the country of Georgia died today after a high-speed crash on a track that is the world's fastest and has raised safety concerns among competitors. A tearful IOC president Jacques Rogge said the death hours before the opening ceremony "clearly casts a shadow over these games."

Nodar Kumaritashvili lost control of his sled during training, went over the track wall and struck an unpadded steel pole near the finish line at Whistler Sliding Center. Paramedics and doctors were unable to revive the 21-year-old luger, who died at a hospital, the International Olympic Committee said.

"We are heartbroken beyond words," said John Furlong, chief executive of the Vancouver organizing committee.

Before speaking at a news conference, Rogge took off his glasses, rubbed his eyes and said, "Sorry, it's a bit difficult to remain composed."

"Here you have a young athlete that lost his life in pursuing his passion," Rogge added. "He had a dream to participate in the Olympic Games. He trained hard and he had this fatal accident. I have no words to say what we feel."

Rogge said he was in contact with Kumaritashvili's family and officials from the Georgian government. Georgia's Olympic committee was deciding whether to remain in the games, Rogge added.

An investigation into the crash started quickly, although Rogge said this was not the time to talk about it. The men's luge competition is to begin Saturday afternoon. Officials at the Whistler track were uncertain if the schedule would be affected.

Rescue workers were at Kumaritashvili's side within seconds. Chest compressions and mouth-to-mouth resuscitation started less than one minute after the crash, and he was quickly airlifted to a trauma center in Whistler.

The first sign Kumaritashvili was truly in trouble came only three seconds before the crash on Curve 13, the most perilous turn. His speed of 89.4 mph — his best during six training runs on this track — almost certainly means he had never gone faster.

Kumaritashvili's line — as the path is known in luge — entering the next-to-last curve had him traveling along a higher route than most racers prefer. That's where it got especially dangerous. His 176-pound body was no match for the gravitational forces along that sweeping turn. That, plus the high rate of speed, sent him careening up the high, banked, ice-covered wall.

Sliding diagonally down the wall, Kumaritashvili hit the corner entering the final straightaway with his lower body. The impact knocked him off the sled and flying across the track, his arms and legs flailing.

After smashing into the pole, he was motionless on a metal walkway. His left leg was in the air and his left foot was propped atop the track wall when the first rescue worker arrived and placed both hands on his helmet.

The rest of men's training was canceled for the day, with VANOC officials saying an investigation was taking place to "ensure a safe field of play."

The danger of the Whistler track has been talked about for months — particularly after several countries, including the U.S., were upset over access restrictions for everyone but Canada, with some noting it could lead to a safety issue.

Kumaritashvili is the fourth competitor to die at the Winter Games and the first since 1992.

"It's a very rare situation," three-time Olympic champion and German coach Georg Hackl said before learning of the death, clearly shaken after seeing Kumaritashvili tended to furiously by medical workers.

Shortly before the accident, Hackl said he didn't believe the track was unsafe.

"People have the opinion it is dangerous but the track crew does the best it can and they are working hard to make sure the track is in good shape and everyone is safe," he said. "My opinion is that it's not anymore dangerous that anywhere else."

Five-time Olympian Mark Grimmette, chosen as the U.S. team's flag bearer, said the speeds on the track are pushing the boundaries of safety.

"We're probably getting close," he said Thursday. "This track is fast and you definitely have to be on your game. ... So it's definitely something they are going to have to take into account on future tracks."

American luger Christian Niccum crashed during a World Cup event in Whistler last year.

"When I hit that ice going 90 mph it turns into fire," Niccum said Thursday. "I remember coming around to the finish and I just wanted to rip off my suit, 'I'm on fire. I'm on fire.'"

This was Kumaritashvili's second crash during training for the games. He also failed to finish his second of six practice runs, and in the runs he did finish, his average speed was about 88 mph — significantly less than the speed the top sliders are managing on this lightning-fast course.

It was unclear how fast Kumaritashvili was going, although many sliders have exceeded 90 mph on this course. More than a dozen athletes have crashed during Olympic training for luge, and some questioned whether athletes from smaller nations — like Georgia — had enough time to prepare for the daunting track.

At the finish area, not far from where Kumaritashvili lost control, athletes, coaches and officials solemnly awaited word on Kumaritashvili before eventually being ushered away. Access to the crash area was closed within about 30 minutes.

"I've never seen anything like that," said Shiva Keshavan, a four-time Olympian from India.

Representatives from the three U.S. sliding federations were to release a joint statement later Friday. American athletes were not immediately made available for reaction after news of the death was confirmed.

"My thoughts and prayers are with the Georgian Olympic team," U.S. bobsled pilot Steven Holcomb said on Twitter. "The sliding community suffered a tragic and devastating loss to our family today."

"RIP Nodar Kumaritashvili," wrote American skeleton athlete Kyle Tress, who did not qualify for the Olympic team. "Let's never forget how dangerous these sports can be."

Kumaritashvili competed in five World Cup races this season, finishing 44th in the world standings.

Earlier in the day, gold-medal favorite Armin Zoeggeler of Italy crashed, losing control of his sled on Curve 11. Zoeggeler came off his sled and held it with his left arm to keep it from smashing atop his body. He slid on his back down several curves before coming to a stop and walking away.

Training days in Whistler have been crash-filled. A Romanian woman was briefly knocked unconscious and at least four Americans — Chris Mazdzer on Wednesday, Megan Sweeney on Thursday and both Tony Benshoof and Bengt Walden on Friday in the same training session where Zoeggeler wrecked — have had serious trouble just getting down the track.

"I think they are pushing it a little too much," Australia's Hannah Campbell-Pegg said Thursday night after she nearly lost control in training. "To what extent are we just little lemmings that they just throw down a track and we're crash-test dummies? I mean, this is our lives."

At the 1992 Albertville Games, Nicholas Bochatay of Switzerland died after crashing into a snow grooming machine during training for the demonstration sport of speed skiing on the next-to-last day of the games. He was practicing on a public slope before his event was to begin.

Australian downhill skier Ross Milne died when he struck a tree during a training run shortly before the 1964 Winter Games in Innsbruck, Austria. British luger Kazimierz Kay-Skrzypecki also died in a crash during training in Innsbruck.

At the 1988 Calgary Games, an Austrian team doctor, Jorg Oberhammer, died after being hit by a snow grooming machine.
