100 metres in a 25-metre pool: read race distance and pool length separately
Count lengths and turns in a 100-metre example, then label the pool before comparing swimming times. Avoid mistaking a pool measurement for the race distance.
A swimming listing can show both the race distance and the pool length. A 100-metre race in a 25-metre pool is still 100 metres: the swimmer covers more lengths, not a shorter event. Before comparing two recordings or finishing times, label those two measurements separately.
Give each number a label
Start with the event name, such as 100 metres freestyle. Then find the pool length in the organizer's information: for this comparison, 25 metres or 50 metres. Do not assume that every “25m” beside a competition title describes the distance of the race being shown.
The French swimming federation's explanation notes three turns in a short-course 100-metre race, compared with one in long course. That is a useful viewing cue, but the event information remains the better way to identify the pool. Camera cuts can hide a turn.
Count a 100-metre example
Imagine two complete recordings of an individual 100-metre freestyle race, both measured in metres.
- In a 25-metre pool, four lengths make 100 metres. The swimmer turns after 25, 50 and 75 metres, then finishes at 100.
- In a 50-metre pool, two lengths make 100 metres. The swimmer turns after 50 metres, then finishes at 100.
Write “distance: 100 m; pool: 25 m” beside the first recording and “distance: 100 m; pool: 50 m” beside the second. The extra turns do not add extra race distance. These are arithmetic examples, not observations of a particular athlete's performance.
Compare like with like
Make a small comparison card with the athlete, stroke, race distance, pool length, date, round and published finishing time. Keep a missing field marked as unknown rather than filling it from memory. If a listing uses yards, preserve that unit; do not silently treat it as metres.
If one time is lower, you can report that numerical difference. Avoid presenting it as proof of improvement under identical conditions when the pool lengths differ. To discuss a record, check the exact category and status published by the governing body or organizer instead of comparing two unlabelled times.
When reviewing the video, watch one continuous length and its turn before jumping between clips. Use a split only after identifying the distance it refers to. Do not count a replayed camera angle as another length of the race.
