Skier Chemmy Alcott won the British downhill title before retirement as she finished top of the podium at the championships in France.
She added the downhill title to the super-G one she won on Sunday.
Her fiance Dougie Crawford, also took the speed double in Meribel with victories in the men's downhill and super-G.
She was selected for the Sochi Winter Olympics, finishing 19th in the downhill. She said: "After winning my last ever super-G on Sunday I put a lot of pressure on myself to win my last senior downhill on such a challenging hill."
Alcott took the downhill title for the seventh time and was four seconds ahead of Cara Brown in second place with Darcie Mead claiming third.
"There are a few promising girls coming up so I think it's really important to nurture those talents to go the whole way," she added. "It's great to be here to offer advice and technical help to my peers."
The British Freestyle Skiing and Snowboarding Championships are also taking place this week, in Tignes, France, with Emily Sarsfield and Ed Drake winning the ski cross titles.
At the World Junior Freestyle championships in Italy, snowboarders Rowan Coultas and Katie Ormerod finished on the podium in slopestyle.
Winter Olympian Katie Summerhayes, who came seventh in Sochi, will compete in the ski slopestyle on Thursday, alongside her sister Molly and Anna Vincenti.
