Paula Walker: "I've no realistic placement for myself"

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.
