The Kingston teen was also the only swimmer to cross the 20-kilometre lake using the physically demanding butterfly stroke, a decision she said she made to increase the difficulty of the trek that took her 7 hours, 47 minutes and 30 seconds.

Maybe, maybe not. Different people get shoulder problems from different strokes. For me it's back crawl and occasionally front crawl that cause problems, fly is no problem (for my shoulders). Admittedly I wouldn't consider 20km of fly!
