Wimbledon's Sophie Hosking and her lightweight women's double scull partner Hester Goodsell had to settle for silver at the rowing world cup meeting in Lucerne last weekend.
The Great Britain pair, who were gold medal winners in Munich at the season's opening world cup, finished second best to 2010 world champions Canada but did finish ahead of the Americans.
Canada hit the front of the field after 500m and behind them the British overtook the Americans to tuck into second place and held onto that slot despite a significant push from the Americans in the final quarter of the race.
The British boat could not, however, make inroads into the Canadian lead and had to settle for silver.
"Obviously it feels a bit flat not to win", said Hosking.
"We know that we have things we can improve and I am really looking forward to getting away on training camp."
Hosking and Goodsell will expect to be named in the Great Britain rowing team for this year's World Championships when it is announced on Tuesday.
