Who are the swimmers (current and past) that anyone who's starting to learn about swimming need to know?
Lynne Cox. I mean the list is long, and most probably know those who were Olympic/World champions and the like. But I think she’s a very accomplished swimmer outside of usual realm of competitive swimming.
Great name! Any other open water swimmers you'd like to throw out there?
Diana Nyad
