It's not just swim fans that are in awe of Katie Ledecky's Olympic dominance ... 'cause USA gold medalist Nic Fink tells TMZ Sports he has no idea how she does it, either!!
Ledecky continued to make history during the 2024 Paris Games ... bringing home four medals over the course of the competition to become the most-decorated U.S. female Olympian.
We sat down with Fink while he was working an honorary shift at Raising Canes in Dallas, Texas on Monday .
