LIVIGNO, Italy — The fans from the Czech Republic clanged cowbells and waved their red-white-and-blue tricolor for a sun-splashed Olympic victory they simply knew was coming.
Then, they all looked down and checked their programs.
Their favorite speed racer, Ester Ledecka, her quest for a third straight title vanquished early, was a mere spectator Sunday when another Czech, eight years younger and without a single big-time win in her career, zoomed across the line to keep the gold medal in snowboarding's parallel giant slalom safely in the republic.
Her name: Zuzana Maderova.
''I can't believe it now," the 22-year-old said, ''but I'm an Olympic champion.''
A few hours after Lindsey Vonn wiped out on an Alpine downhill course a mountain range away in Cortina D'Ampezzo, Ledecka — and Maderova — reinforced the obvious to the Winter Olympic world: There are no sure things when these racers hit the slippery ice and snow.
''Suddenly, I made a mistake in the quarterfinals,'' said Ledecka, who skittered and put her hand down at the sixth gate in the quarterfinal, costing her precious time and a chance at another title. ''I did my best. It's what can happen in this sport.''
Her country's president, Petr Pavel, came to Livigno expecting to celebrate a win. It was a good bet. Ledecka hadn't lost a PGS race in nearly two years or missed a podium in five.
