Choose the pool length to convert yardage into lengths: a 2,000 yard workout is 80 lengths of a 25 yard pool or 40 lengths of long course.
How to write a swim workout
Write one set per line. Start with the number of repeats and the distance, like 4x100 or 8 × 50; a single swim is just the distance, like 400. Add what to swim, such as free, kick, pull, drill, IM or easy. Then add an interval with @, for example @1:45, or a rest with rest 15. Lines like Warm-up, Main set, Kick set, Pull set and Cool-down start a new section, and lines starting with # are notes.
SwimCard totals each section and the whole workout, converts the distance into lengths for your pool and works out the time. Sets on an interval are exact; sets without one are estimated from the easy pace per 100 you enter, so the time is labelled as approximate.
Structuring a good practice
Most workouts follow the same shape: an easy warm-up of 10 to 20 percent of the total, some drill or kick to work on technique, a main set where the real work happens, and an easy cool-down. Keep intervals honest; if you are getting less than five seconds rest on aerobic repeats, add time to the send-off.
