Carlo Janka and Lindsey Vonn claimed overall World Cup titles after skiing to victory in events at Garmisch-Partenkirchen.
Janka followed up on his gold medal in the giant slalom at the 2010 Winter Olympics on the Whistler course with another scintillating run in the same event in Germany.
He had already set the fastest time in the morning run before the 23-year-old Swiss star continued where he left off to win the event with an overall time of 2:20.87 ahead of Italy's Davide Simoncelli.
Janka now holds an unassailable lead in the men's standings with just the slalom event in Germany remaining and becomes the first Swiss male to take the overall title since Paul Accola achieved the feat in 1992.
According to the AFP, he said: "I knew that I had to win here and I was really pleased with the second run. Everything has come together for me this season and I have won everything that there is to win.
"It also all came together today for me - the weather, the snow, everything was perfect. I took the feeling all the way down to the finish line in the exact way I wanted to."
Janka now sits on 1,197 points for the season and with only 100 points up for grabs in the slalom, second-placed Benjamin Raich is unable to catch him after finishing eighth in the giant slalom.
Meanwhile, Vonn was already assured of a third successive overall World Cup title before leaving the start gate of the female super G event after Maria Riesch had failed to finish in the first two.
However, the Olympic downhill gold medallist did not disappoint her fans as she cruised to victory to become the US skier with the most World Cup race victories in history - surpassing Bode Miller's record of 32.
Vonn posted the fastest time down the Kadahar course of 1:19.30, with Austria's Elisabeth Goergl taking second in the race and Nadia Styger of Switzerland claiming third.
She also posted a US record of 11 wins in a single World Cup season and becomes the first women to take overall victory three years in a row since Petra Kronberger between 1990 and 1992.
Vonn said: "An overall title is one of the biggest things you can win in our sport. I gave it all I had. I have nothing more left in me."
She will now take the slalom off to rest her knee that she injured in a crash in the giant slalom in Germany.
