In the Olympics, a swimmer has the potential to win a surprising number of medals. The total depends on how many events they participate in and of course, how well they perform. Individual swimmers can participate in up to seven different events, which means they potentially have seven opportunities to win a medal. However, when you add relay races into the mix, this number can increase even further. So, theoretically, an Olympic swimmer can win quite a lot of medals, provided they're at the top of their game!
