A 100-meter sprint needs hundredths-of-a-second display and instant lap capture, while a marathon needs simple accumulated time with occasional split notes. Use this reference table to find the right tool for your event. Coaches timing training intervals will find the Interval Timer especially useful for structured workout sessions. How to Time a Race Accurately Timing accuracy comes down to consistent technique. Even a precision device gives poor results with poor operator practice. Follow these principles for reliable splits every time. For workout planning beyond race day, the For Coaches page has additional tools and suggestions. Positioning at the Finish Line Stand directly level with the finish line, not behind or in front of it. Your line of sight to the tape or marker should be perpendicular to the direction of travel. Looking at an angle introduces parallax error - you press the button when the athlete appears to cross, but they may still be a meter away. For track events, position on the inside of the track at the finish line. For road races, stand on the side of the road at the finish marker. Accounting for Reaction Time All hand-timing introduces a reaction time error of approximately 150–250ms. For training purposes this is irrelevant - the same error applies to every measurement and comparisons remain valid. For results that will be compared against certified times, note that official hand-timed results in athletics typically add 0.24 seconds to sprint times to account for this difference. For training logs, simply record raw times consistently and compare them to each other. Using Multiple Timers as Backup For important races, always have a backup timer. Open two browser tabs with the Lap Stopwatch, or assign two timekeepers. Start both simultaneously. If one misses a split (fumbled button press, distraction), the backup preserves the result. For multi-lane swimming or field events with many athletes finishing close together, assign one timer per expected cluster of finishers. Recording Results After finishing, use the Lap Stopwatch's Export CSV button to download all splits instantly. The CSV file opens in any spreadsheet application and includes lap number, split time, and cumulative time for every recorded lap. For swim meets or athletics carnivals, this exportable record eliminates manual transcription errors. At busy finish lines, a second helper with the online tally counter can count finishers as they cross while the timekeeper focuses on splits. Understanding Lap Times and Splits A split is the time recorded at a specific point in a race - a lap boundary, a kilometer marker, or a relay exchange. Analyzing splits reveals whether an athlete ran even pace, went out too fast, or saved energy for a strong finish. Use the Lap Stopwatch to record every split automatically during a race without resetting between athletes. World Record Race Times - Speed Comparison The chart below compares world record times across different distances on a relative scale. Because the events have vastly different durations, bars represent relative performance within each event's context - longer bars indicate greater dominance over the previous record, not absolute speed. Relative bar width = percentage of previous world record improvement (all-time as of 2024). Frequently Asked Questions For training, school sports, club events, and recreational racing, yes - absolutely. The timing precision is sub-millisecond. For certified official results in sanctioned athletics competitions, regulations typically require World Athletics-approved electronic timing systems with photo-finish technology. Check your event's governing body requirements before using any non-certified system for official records. For fitness training where exact race certification is not required, also see the For Workouts tools collection. Open the Lap Stopwatch and start it at the gun. Press the Lap button (or Space bar) each time a racer crosses the finish line. Each press records a cumulative time you can annotate later with the athlete's name. Alternatively, open multiple browser tabs - one per lane - and start them simultaneously for independent tracking. Download all results via the CSV export at the end. The timer itself does not measure wind speed - you will need a certified anemometer for that. For reference, World Athletics allows wind assistance of up to +2.0 m/s for records to stand in sprints and horizontal jumps. Record the wind reading manually alongside your stopwatch result. For training purposes, wind conditions are worth noting in your records even without official measurement, as they provide valuable context when comparing performance across sessions. For close races where manual timing cannot separate two athletes, the most practical low-cost alternative is video timing: record the finish with a smartphone camera at 60fps (or 120fps slow-motion if available), then review frame-by-frame. At 60fps, each frame represents approximately 16ms - more than enough resolution for most amateur events. Some coaches use dedicated sports timing apps with video sync for exactly this purpose. Yes. The stopwatch uses a timestamp-based system rather than a tick-based counter, so it continues counting accurately even when the tab is in the background, the screen is locked, or the browser is minimized. The displayed time will update instantly when you bring the tab back into focus. This makes it safe to use alongside other apps during a race without losing time.
