Above are the fastest times that Jonathan Kern has achieved in his swimming career. For each event, you can find Jonathan's best time, the corresponding time standard, as well as how much faster Jonathan needs to be to reach the next level.

These rankings are based on the Jonathan's personal best, his current age category, and team; and are calculated from all the meets results.
