Competing at the French Alps track, Walker also backed up the following day in the two-woman Bobsleigh event alongside brakewoman Kiara Reddingius, finishing in seventh place in their first event back together since the 2022 Olympic Winter Games and equalling their personal best result in IBSF World Cup.
In the monobob, Walker had an impressive first run, with the equal second fastest time on the La Plagne track along with German Laura Nolte in a time of 1:04.05 seconds,
In the second run, where the top competitors go in reverse start order, conditions unexpectedly got slower as the event progressed disadvantaging the fastest sliders from the first run. Walker finished with the equal sixth fastest run, again with Nolte again recording the same time in 1:04.27 seconds, giving them both a two-run time of 2:08.32.
Taking the win was American Kaysha Love in an incredible World Cup debut with a two run time of 2:07.92, with Swiss driver Melanie Hasler in second and Andreea Grecu of Romania in third.
Next up was the two-woman, with Walker and Reddingius finishing the first run in eighth place in a time of 1:01.84 seconds.
The pair went faster in run two, with the sixth fastest time of the round in 1:01.38, giving them a two run time of 2:02.22, 0.98 seconds behind event winner Nolte and Schuten of Germany.
"It's one of the most beautiful places on the tour, so we have thoroughly enjoyed being here," said Walker.
"The track was a little bit bumpy, but we made it work, and ultimately walking away with a solid result and we just build from here."
"I have a brand new team in terms of new coaches and then also Kiara is back, so we just need to get back in the groove of things, but to walk away with a fifth in the monobob, and seventh in the two-woman with Kiara which equals our best ever result so far, so really happy with that.
"The altitude is pretty rough up here, I am pretty excited to get back to lower altitude, but you have to make it work, everyone is dealing with the same conditions, so we just made the best of what we could this weekend."
Walker will be aiming for the podium at the World Cup next weekend in Innsbruck, Austria, a location she has had great success previously.
