The opening day belonged to the Czech Republic with Jiri Prskavec and Amalie Hilgertova leading the way.

The morning began with the U23 K1M heats.
Prskavec showed his class executing a clean and fast run down the technical 23 gate course to win the U23 K1M heat in 88.43.
The 2013 senior World Championship silver medalist finished 0.55 seconds ahead of American Michal Smolen.
Italian Zeno Ivaldi was third fastest after putting together a fast second run of 91.71 down the 2000 Sydney Olympic course.
Victorian Jaxon Merritt lead the Australian charge in seventh, 4.72 seconds behind Prskavec.

Polaczyk found the course a little bit tough on his first run but improved in his second to record the sixth fastest heat time.
“There isn’t much space. It wasn’t the fastest time. Six points was pretty stupid, but I will be better on the next run”, Prskavec said.
The U23 K1W heat followed with Jessica Fox topping the timesheet in 101.00, 0.13 seconds ahead of Karolina Galuskova who continued the Czechs excellent start in Penrith.
“It has been really good to get out there and race today and I am excited for the next few days of racing”, said Fox.
Italian Stephanie Horn recorded the third fastest time of 102.12.
“I like the course, it is very nice to go from the upstream to the next downstream and the boat is running so you have a good feeling so it is a nice course”, Horn said.
Australian pair Alison Borrows and Georgia Rankin qualified for the semifinal in 18th and 25th respectively.
British kayaker Kimberley Woods also progressed through to the semifinal after recording the ninth fastest heat time.
Woods won silver at last year’s Junior World Championships and steps up to U23 competition this year.
It is Woods first time competing at Penrith Whitewater Stadium.
“It is the first time I have been here and it is very good and very different to what I am used to”, Woods said.
Woods is aiming to make the final.
“Hopefully final, it is my first year of U23s and it would be really nice to get a good result but I am here to just do my best really.”
