How to read your splits
Each row compares your cumulative split with even pacing to the goal. A green minus means you are that many seconds ahead of schedule; an amber plus means behind. The projected finish assumes you hold your average split pace so far for the remaining splits.
Even pacing is not always the plan. In middle-distance racing the fastest times usually come from even or slightly negative splits (a slightly quicker second half). A big positive split, where later laps are much slower, is the classic sign of starting too fast. Use the pace calculator to plan split times for any distance first.
Typical uses
- Track sessions: 400 m reps in a 1600 m effort, with 4 splits and a goal like 6:00.
- Road races: 1 km or 1 mile markers against a goal marathon or 10 km time.
- Swimming: 50 m splits in a 400 m set.
- Speedruns and presentations: checkpoints against a target run time or slot length.
Questions people ask
What is a split timer?
A split timer records the cumulative time at each checkpoint of one continuous effort. This one also compares every split with the time you need for your goal, so you see how far ahead or behind you are.
How is the target split calculated?
Goal time divided by the number of splits, i.e. even pacing. Split k should be reached at k × target split. The ahead/behind figure is your actual cumulative time minus that.
What happens after the last split?
The timer stops automatically when you record the final split, so your finish time is exact. You can export all splits as CSV.
