The Norwegian, who won both the downhill and super-G in Lake Louise last weekend, clocked a time of 1:42.04 down the challenging Birds of Prey course.
He finished 0.18 seconds ahead of Guillermo Fayed of France, with Siegmer Klotz again ending the day in the top three after posting a time 0.36 off the pace.
Svindal managed the fifth best time during the first training session and did not feature at all in the top 10 after the second run, but the two-times overall World Cup champion said his plan was always to improve as the week progressed.
“My approach these three days was to take it easy in the beginning,” Svindal said. “In second training I tested some equipment and it didn’t work well – but with three trainings you can do that.
"My skiing was not there yesterday so last night I spent a lot of time watching videos, and I watched the best run but mostly focused on watching what I did and trying to figure out how to clean it out.
"The bottom line is you can’t have slow sections in this race if you want to be competitive."
Svindal suffered a big crash at Beaver Creek five years ago, an incident which he says has helped him get to know the course better year on year.
“I skied this course in my head so many times after my crash that I can really say I know it well,” he says.
“This year I feel more stable than last year, I was leading the overall up until New Year and that’s when (Marcel) Hirscher and (Beat) Feuz started winning everything.
"This year the goal is to be consistent through the whole season. Feuz is not here but Hirscher and probably Ted Ligety will be able to challenge me.
"I have been working on that, as last year super-G was good last year but downhill and giant slalom had too many ups and downs. I want to race every race for a top finish, and even if I don’t get it, now I know at least that I am there among the best.”
The first downhill race of the week is scheduled to take place at 10.45 local time (5:45pm in the UK).
