Split Time Stopwatch
Splits versus laps
A split is cumulative — press it at each checkpoint and you get the total time from the very start to that point. That’s the number you compare against a target pace when you’re working through something long.
This page shows both figures side by side: the running split, and the time for the segment since your last press. Reading the two together is how you spot a fast section rather than just a fast start.
Why anyone bothers with negative splitting
Running the second half of something faster than the first — negative splitting — is the pacing pattern behind a large share of distance records, precisely because starting conservatively leaves more in reserve than it costs.
A single finishing time can’t show you that pattern. Splits can: they’re the difference between knowing what happened and knowing why it happened.
Questions people ask
How is this different from the plain stopwatch?
The stopwatch shows one running total. This page tracks each segment against the cumulative time as well, which is what pacing actually requires.
Can I export my splits afterward?
They live in the page only, so copy anything you want to keep before refreshing or navigating away.
