Lindsey Vonn is showing off her fit physique while enjoying a tropical getaway.

The retired Olympian posed for a photo in a bright red bikini alongside her dog, Lucy, while strolling the beach. The 35-year-old has appeared to be enjoying a break with her canine companion in the last couple of days but refused to spill details on just where she was.

"Just 2 girls on a crazy adventure...#secretproject," Vonn captioned the photo.

Vonn's backside was facing the camera as she smiled with her hands on her hips, leading to fans praising the former pro skiier in the comments section.

Vonn's fiance, NHL star P.K. Subban, seemed to enjoy the sexy snap, proudly writing, "CRAZZZZY glutes."

Days prior, Vonn celebrated reaching 2 million followers on the photo-sharing platform with another touching photo next to her dog.

In July 2018, Subban gushed over his partner to Fox News.

“I haven’t met anyone who’s tougher than her yet,” Subban said of Vonn. “But what she’s gone through — just how she’s done it and how she’s managed to bounce back from those serious injuries and remain at the top, I don’t think I know another athlete that’s been as successful as she has pre-and-post injuries."
