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