The 2022 Olympian made a great start to the event on the difficult Altenberg track with the fastest time of all competitors in the first run in 59.47 seconds.
Making it even more impressive, was Walker had the tenth fastest start time, but then showed her impressive driving skills to work her way to the fastest time of the round.
In the second run, the third last competitor Elana Meyers Taylor of America had a fall which resulted in a delay which slowed the track down for the final two competitors and leaders from the first run, Debora Annen of Switzerland and finally Walker.
Walker finished her second run in a time of 1:01.13 seconds, which was the seventh fastest of the round, pushing her back to fifth place with a two run total of 2:00.60 seconds.
Taking the win 0.66 seconds ahead of Walker was Laura Nolte of Germany, with her teammate Lisa Buckwitz in second and Andreaa Grecu of Romania in third.
Walker reflected on her performance after the race.
“The fifth is a solid place to start the season. Unlucky to have a crash and a track hold in the snow before my second heat but I accept that can happen in bobsleigh sometimes.
“All in all I am m happy with my drives and how I performed, especially here in Altenberg, it sure has been a journey for me here. Ready to build on that this season.”
Sarah Blizzard made her World Cup monobob and two-woman World Cup driving debut, finishing in 21^st place in the monobob, and 17th in the two-woman with brakewoman Ashleigh Werner.
Walker and brakewoman Kiara Reddingius elected to not compete in the first two-woman bobsleigh events of the season, but will commence their season together in the first event of the new year in Winterberg, Germany.
Next weekend the IBSF tour moves to Sigulda, Latvia, for the next round of World Cup competition.
