Each facility and club on Swim.com will have two leaderboards, one for distance and one for fastest time.
In order for a swim to appear on a club or pool leaderboard, the following conditions must be met:
1) Your workout is publicly visible
2) Your workout has not had its swim data edited
3) You have enabled leaderboards in your account settings
4) You workout is assigned to the pool (facility) or you have joined the club of the leaderboard you are viewing.
The pool distance leaderboard, pictured below, simply ranks swimmers based on the total distance swum at the pool across all workouts.
The pool fastest leaderboard, pictured below, is a ranking of the fastest times over a given distance at a given pool. Entries are ranked from fastest to slowest based on any interval of continuous swimming that is equal to or greater than the distance specified.
You are able to adjust the course length and distance to see different fastest times as well as filter so that your results only show specific groups of swimmers (age, sex, class) as well as narrow results into a certain time frame.
Similarly, each club will also has a distance and fastest (pace) leaderboard that functions in the same manner as above. To find a swim club to join, or to create one, please refer to the instructions on this page: https://support.swim.com/hc/en-us/articles/201553049-Club-Pool-Search
