Great Britain's Paula Walker has admitted that she has set "no realistic placement" for herself ahead of Monday's bobsleigh event at the 2014 Winter Olympics in Sochi.
The 27-year-old, who will partner Rebekah Wilson, has four top-10 finishes at the World Cup on her record this season.
"I was at the test event here last year but I really struggled," Walker told BBC Sport. "I'm working hard to tell myself everything will be okay because normally I'm a fast learner.
"Vancouver was a very hard track but I quickly mastered it. I need to find the inner vibe you need to get accustomed to a track.
"My last runs here were a bit of a wild ride but until I've done my practice runs I've no realistic placement for myself."
The pair finished in fifth place at last year's World Championships.
