  1. Click here to REGISTER NOW for the Postal Swimtathlon League with Club Assistant..  You don't need your times to register!

  2. Once registered, proceed to the TIME SUBMISSION FORM to submit your times.

  3. Submitted times may be from a meet OR during a practice.  The only timing requirement is a stopwatch and an independent timer/verifier.  This is an honor system event.

  4. With the exception of backstroke, there will be a starting block adjustment of 1.5-seconds per event.  For example, if the submitted time for a 50-yard free was 30.00, “from an in-water push,” then the official time would be 28.50 to compensate for the lack of a starting block.

  5. Swimmers may submit one challenge per month, per event.  For example, in January, a swimmer who submitted 50 free time of 30.00 could improve that time in February to 29.50 and submit that result.  Faster times may be submitted only once per month, per event (Free, Breast, Back, Butterfly, and Individual Medley).  League standings will be posted monthly.

  6. In STAGE FOUR, swimmers may submit faster times for any of the fifteen Swimtathlon League events.  The cumulative times for all fifteen events will determine the final Swimtathlon League standings.

  7. Times may be submitted in any course (SCY, SCM, and/or LCM); however, short course yards will be used for Swimtathlon League standings.  The conversion tool at SwimSwam.com will be used for determination.
