LAKE LOUISE, Alberta (Reuters) - Lindsey Vonn's World Cup rivals want to spoil the American's winning record in this weekend's races in the Canadian Rockies.

Vonn has collected five World Cup downhill victories in five years here but her fellow racers say she should not take more wins for granted.

Holaus, whose only World Cup win came in a super-G in Cortina d'Ampezzo last season, set the pace on a bitterly cold day with a time of one minute 50.95 seconds.

Lake Louise is hosting downhills on Friday and Saturday and a super-G on Sunday.

Holaus, a rising talent on the powerhouse Austrian team who has struggled with injuries, was also fastest in the first training run on Tuesday.

Switzerland's Nadia Styger was second quickest on Thursday in 1:51.23, followed closely by Austria's Andrea Fischbacher, runner-up in the super-G last season.

Vonn, who posted the fastest time in Wednesday's training, was fifth fastest but stood up as she approached the finish line.

"She's really strong on this hill and we know that coming in so we have to be strong too," said Canadian Britt Janyk, who was seventh on Thursday.

"She's got a lot of confidence in her right now and she's got a lot of confidence on this hill.

"I hope that she has a great weekend because when you beat her it feels that much better.

"It's time for a change," Janyk said. "She's had enough."

Team mate Emily Brydon, who was 13th on Thursday, agreed.

"Anyone is beatable, everyone is human, everyone can make mistakes and that's what I'm going to capitalize on," said Brydon. "I'm going to have a perfect run and hopefully she can make a few costly errors.

"But she's on fire. She's skiing amazing and this is a hill she's had a lot of success on, so it's going to be a difficult task but not impossible."
