Due to extreme weather conditions and potentially unsafe roads, Stage 1 of the 2011 Amgen Tour of California was cancelled just before the riders, who were lined up at the start, were about to begin the race.

"We were monitoring weather conditions up until the predicted 1:15 p.m. PT start time, and we just couldn't safely put the riders out on the course with the current forecast," said Andrew Messick, president of AEG Sports. "We appreciate the support of all the fans that came out to the start line in South Lake Tahoe, and we hope they understand and respect our decision, but when the safety of riders and fans is involved, there is no leeway. We are looking forward to seeing everyone at the start tomorrow in Squaw Valley."

As the race was being cancelled, three-time Amgen Tour of California champion Levi Leipheimer addressed the crowd from the sign-in stage and said:

"The riders discussed as a group and we just don't feel comfortable riding knowing what can happen, especially in light of what happened last Monday. We still have a full week of racing ahead of us, so we want to make sure everyone is healthy. With the weather conditions the way they are, racing today is just not possible. On behalf of all the riders, we apologize and appreciate everyone's support and understanding."

The race will continue as planned tomorrow, Monday, May 16, beginning with a neutral start lap through Squaw Village at 10:15 a.m. PT and heading to the finish in Sacramento.
