Seven Swimmers & Two Relays Remain Unbeaten In ISL History

Lilly King is unbeatable.

At least, she has been across two ISL seasons and six individual matches. The Cali Condor has not lost a 50, 100 or 200 breaststroke, nor a medley relay in six meets. She’s an incredible 25-for-25 in ISL event wins.

King’s much-discussed dominance got us curious: what other swimmers are undefeated in a specific ISL event across their careers?

We break down the undefeated below, led by seven swimmers and two relay teams that are unbeaten across two years of competition.

LON would’ve beaten ENS in the 4×100 free at the London meet last year if they didn’t choose to balance their teams for 2nd and 3rd place instead (and more points).
