The opening stage of the 2011 Tour of California has been cancelled due to heavy overnight snowfall and the threat of further adverse weather conditions around Lake Tahoe.
Race organisers had already taken the decision to shorten Sunday's road stage around Lake Tahoe due to the weather. However, several riders had expressed concerns over the safety of racing in such conditions, particularly in the light of Wouter Weylandt's fatal accident at the Giro d'Italia on Monday.
The riders rolled out of South Lake Tahoe but there was some unease in the bunch and a protest was mooted with riders refusing to race. An official decision was made to cancel the stage and the riders returned to team hotels.
More rain, snow and wind has been forecast for Sunday night which may also affect Monday's stage from North Lake Tahoe to Sacramento.
The cancellation of the opening stage is a major setback to organisers who last year had shifted the race from its February slot to May to try and avoid the harsh winter weather of previous editions.
British digital television channel ITV4 had been scheduled to show live coverage of the opening stage.
The eight-day, UCI 2.HC-ranked Tour of California is scheduled to finish in Thousand Oaks on Sunday, May 22.
Six British riders are taking part in the race: Alex Dowsett, Chris Froome, Jeremy Hunt, Ian Stannard, Ben Swift (all Sky) and Charly Wegelius (Unitedhealthcare).
