Naked run in Finland known as Nakukymppi:

At 1:45, we get to watch a lone female runner, then we shift focus to a lovely painted lady with who I assume is her boyfriend or husband. This is my favorite naked run video because of how long it focuses on a single woman, usually I’m looking for the females in the crowd, or only catch glimpses of them since there’s so many. Plus YouTube’s playback speed feature let me get a good look all the jiggly bits in action!
