"I was fourth with 2kms to go and I thought that I really want this bad, so I kept pushing. I passed Varga and the last 1km was hell for me. But I didn't want to finish fourth. Everyone hates getting fourth, it's the worst position ever, so I am so happy all the hard work has paid off."
Australian Gillian Backhouse led from the start of the women's race, first out of the swim with American Summer Cook, and then soloed away on the bike and held on to win in 2:03:29. Local Czech athlete Vendula Fintova, buoyed by the home crowd, ran through to second for her first world Cup podium since New Plymouth two years ago.
Cook held on for third as van der Kaay, who was part of the chase group on the bike, managed to edge out Australians Emma Jackson in the sprint finish for fourth.
Attention now turns to the climax of the year with the ITU World Triathlon Grand Final in Rotterdam in two weeks.
