Swimming Race Timer
Time swim lanes, lap splits, relay exchanges, and interval sets with clear browser-based timers.
Best Setup for Swimming Timing
Swimming timing often needs lane-specific attention, repeat splits, and quick recovery intervals. Use the lap stopwatch for race splits and the interval timer for training sets such as 10 x 100m on a fixed send-off.
| Need | Best Setup | Recommended Tool |
|---|---|---|
| Single swimmer race | Start at signal, stop at wall touch | Stopwatch |
| Lap or length splits | Press lap at every wall touch | Lap Stopwatch |
| Training set intervals | Configure work/rest or send-off rounds | Interval Timer |
Swimming Timing Tips
- Assign one timekeeper per lane when several swimmers finish close together.
- Press lap at each wall touch for split-based training analysis.
- Use interval timing for send-offs, rest periods, and structured swim sets.
- Keep the device dry and visible, ideally away from splash zones.
Send-off intervals and the pace clock
Swim training is organised around send-off intervals rather than rest periods. A set written as 10 x 100 on 1:30 means a swimmer leaves every ninety seconds regardless of how long the swim took - so a 1:20 hundred earns ten seconds of rest and a 1:25 earns five. The rest is the variable, which is what makes the set self-regulating: swim faster, rest longer.
That is why pool decks have a pace clock rather than a stopwatch. Every swimmer needs to read their own send-off from a shared display, usually leaving on the top or the sixty, and a single timer held by the coach cannot serve a lane of eight people departing at staggered intervals.
Race timing is a different problem again. Competitive results come from touchpads at the wall, because the finish is a touch rather than a line crossed and hand timing a wall touch from the deck is unreliable. For training and small meets without pads, backup hand timing is standard - typically several timers per lane, with the middle value taken rather than the average.
Frequently Asked Questions
What does 10 x 100 on 1:30 mean?
Ten repetitions of 100 metres, with a new repetition starting every ninety seconds. The interval includes the swim, so the rest is whatever is left over - a 1:20 swim earns ten seconds of rest. Swimming faster is what buys recovery.
Why do pools use a pace clock instead of a stopwatch?
Because swimmers in a lane leave at staggered intervals and each needs to read their own send-off time from a shared display. One coach with one stopwatch cannot start eight swimmers departing five seconds apart, so the clock on the wall does the job instead.
