Predicted inclement weather forced organisers to move seeding from Friday to Thursday, with finals now scheduled for earlier in the day on Friday.
Kennedy-Sim was sixth to go in the seeding round, crossing the line with a time of 1:14.97.
She finished ninth overall and 1.86 seconds off the pace, which was set by Canada’s Marielle Thompson.
The Sochi Olympian was happy to blow away some of the cobwebs and post a strong run.
“I had my worst run ever in training this morning, so to get those Olympic nerves out of the way was a good thing,” Kennedy-Sim said.
“My start was really strong but I’ve got some elements that I need to clean-up. Looking good going into a race tomorrow, it will be fun,” she said.
Kennedy-Sim knows she’ll need more than a strong start if she is to move through Friday’s finals.
“Always something I can rely on but on this track, we had quite a bit of passing in the training days and there was crazy passing yesterday in the men’s (event).
“Fair game, everyone has a bullseye on their back here.”
The 29-year old takes confidence from her previous Games experience.
“I learnt that anything can happen at an Olympics. The cool thing is you don’t have to worry about the qualifying run because you’ve already qualified. Takes the pressure of a little bit.
“Win lose or draw, if I can inspire a couple of kids at home to get off the couch and get active – that’s the best thing, that’s what the Olympics is about,” she said.
Women’s Ski Cross finals begin 9am local time (11am AEST) on Friday 23 February (Day 14). Kennedy-Sim will start in heat two in the round of eight finals.
Finals consist of 1/8 finals, quarterfinals, semifinals, small final and big final. The competitors are placed in the heats of the first phase (1/8 finals) based upon their seeding. Each heat can have a maximum of four competitors with the first two competitors of each heat advancing to the next phase.
