First up was a two-woman race, with Walker and Reddingius achieving their best result of the weekend in fifth place, just 0.67 seconds behind the event winners Kim Kalicki and Leonie Fiebig of Germany.
On day two Walker competed in the monobob, finishing in ninth, 1.15 second behind German pilot Lisa Buckwitz in first place.
The third and final day featured another two-woman World Cup, with Walker and Reddingius finishing the first run in seventh.
Unfortunately in the second run, the pair had a fall in the bottom section of the Sigulda track, causing the sled to slide across the line on its side, putting them in 13th place.
The next World Cup will take place in Altenberg, Germany, on February 17-18.
