Britain's Alex Coomber showed her world champion class when she finished the second Olympic training day at the top of the pack.
The skeleton slider, favourite for gold in Wednesday's event, was first in both of Monday's practice runs at Utah Olympic Park.
She edged out American Tristan Gale by 0.02 of a second. Three sliders shared third place, Switzerland's Maya Pedersen, America's Lee Ann Parsley and Canada's Michelle Kelly.
On Sunday, Coomber had been disappointing by her standards when she could only finish fifth after the first two runs.
The training run times do not count at all when it comes to race day, which is at 1600GMT on Wednesday.
All racers will start with a clean sheet and the fastest over two runs will win the gold medal.
In the men's competition, Britain's Kristan Bromley had two solid runs to finish in equal 10th position.
