I've never done much competitive/team swimming, but in all my years being around pools for my own fitness swimming, and lifeguarding...I had never seen nor even heard of this m.youtube.com/watch (it's a video I found on the internet). But while lifeguarding today I saw two women doing this during the lap swim session. They did a 800 tandem medley. Each would swim 100 in front, all four strokes. Interesting.
