Cawthorn is the European 1,000m champion
Britain's Rachel Cawthorn produced a superb display to win bronze in the women's K1 500m at the World Cup meeting in Racice, Czech Republic.
Cawthorn, who missed months of winter training because of a virus, fought back from sixth place to finish third.
"I'm in shock and speechless. It was a surprise to see I was third following such a difficult winter," she said.
The women's K4 500m quartet of Abigail Edmonds, Jessica Walker, Hayleigh Mason and Louisa Sawer won a silver medal.
