Above are the fastest times that Kathryn McGuffin has achieved in her swimming career. For each event, you can find Kathryn's best time, the corresponding time standard, as well as how much faster Kathryn needs to be to reach the next level. The last columns provide Kathryn rankings at the team and LSC levels. These rankings are based on the Kathryn's personal best, her current age category, and team; and are calculated from all the meets results.
