Rogers praying for consistent conditions

The Australian is a three-time world champion in the discipline and one of about eight riders who are realistic medal chances over the 44km course at Hampton Court, near London.

Rogers rode over the course on Tuesday and said his legs are feeling strong after the Tour de France and Saturday's Games road race.

But his big concern is what the weather will do, with a forecast of windier conditions for Wednesday.

An hour or so of rain in the midst of the time trial schedule would dramatically affect the standings, because wet roads force riders to slow down on corners.

"I don't really mind what the conditions are, so long as it's the same for everyone," Rogers said.

"I know it is hard, because they go through waves (of starters), it's spread over quite a long time.

"I'd hate to see 'X' amount of years thrown away because the weather conditions are different."

Rogers' Sky teammate and Tour champion Brad Wiggins is the gold medal favourite, with German Tony Martin and Swiss ace Fabian Cancellara also strong medal chances.

Cancellara will start despite the arm injury he suffered in a crash late in the road race.
Rogers is also quietly confident about his chances.

"I like it (the course),  it's fast, I have good legs and it's a good course for me," he said.

"I can only go off the past, can't I.

"For the one-day time trials I'm always up around the mark.

"I certainly hope to go a good ride, I feel fresh today, that's a good sign."

Rogers did not excel in the two long Tour time trials earlier this month, but that was not his job.

His role was to support Wiggins through the mountains and he and compatriot Richie Porte did that to perfection.

Cadel Evans was also supposed to ride the time trial, but he pulled out on Sunday because of post-Tour fatigue.

"He was physically tired. He obviously knows himself better than anyone in a one-day time trial," Rogers said.

"If he's not fresh, it is hard, you're off that few per cent.

"In a one-day time trial, it's all about freshness, it's different to a Tour time trial."
Rogers said Sky team-mate and Wiggins' British compatriot Chris Froome, who finished second in the Tour, was also a medal chance in the time trial.

"But there are a bunch of guys on their day who can be around the medals," he said.

"If I'm on a good day, I can definitely medal."
