Great Britain's David Florence took gold in the men's C1 on day two of the Canoe Slalom World Cup in Cardiff.
After high winds and persistent heavy rain at the Cardiff International White Water Centre forced the cancellation of Friday's opening day, Florence gave the home crowd something to smile about.
He sauntered into the final in first place with a time of 99.74 seconds and was helped after double Olympic champion Michal Martikan finished 15th in his semi-final.
Despite being the last boat to go, Florence held his nerve and executed the off-set sequence perfectly to post a time of 100.46 seconds and take the win ahead of Russia's Alexander Lipatov and Alexander Slafkovsky of Slovakia.
Florence said: "My semi-final had gone spot on to plan and I was just looking to repeat that.
"To win a World Cup gold at this level of racing is incredible as they don't come round very often and to do it on home soil just means a huge amount. It is also a huge boost ahead of the Olympic Games."
GB head coach Jurg Gotz added: "We always planned to target the European Championship and the World Cup here in Cardiff on home soil to test how our preparations are going for the Olympic Games and David certainly gave a stand-out performance."
In the women's C1, Mallory Franklin took bronze - behind Australian duo Rosalyn Lawrence and Jessica Fox - with 16-year-old Kimberley Woods finishing fourth in her first World Cup.
