While most high-end fashion designers are showcasing their wares on the catwalk at Fashion Week, Stella McCartney (search) is hitting the gym.

McCartney and the athletic shoe company Adidas (search) have joined as unlikely partners to create a line of women's sportswear.

The line, "Adidas by Stella McCartney," features clothes and shoes for running, the gym and swimming. Scheduled for two roll outs a year, the first collection will hit stores in Feb. with prices ranging from $48 to $243.

"Women take both — their sport and their style — seriously," McCartney said. "Why should we have to sacrifice one for the other?"

McCartney, the daughter of the famous Beatle, collaborated with Adidas in 2002 for a limited design sneaker.

The designer has her own fashion house under her name in partnership with the Gucci Group.
