How to Use This Splits Calculator
Pick your race distance, enter a goal finish time and choose km or mile splits. The table shows the time for each split, the pace needed and your elapsed time, so you can write the key checkpoints on a pace band or load them into your watch. Choose a negative split to start 2% slower and finish 2% faster without changing your finish time.
Even, Negative and Positive Splits
Even split: the same pace throughout. Simple, and a solid plan on a flat course.
Negative split: a slower first half and faster second half. Most runners finish stronger with it, because the early kilometres feel easy and it is tempting to run too fast.
Positive split: a faster first half. It rarely works over the marathon, since extra early effort costs more than it saves later.
Pacing the Marathon in Four Stages
Many coaches break the marathon into stages: settle in over the first 10K, hold goal pace to 30K, then run the final 12K by feel. The checkpoint times above give you the first three markers. For paces beyond your goal, see the marathon pace calculator for training zones, and the pace converter to switch between min/km and min/mile.
Frequently Asked Questions
A negative split means running the second half of a race faster than the first. It is the most reliable way to finish strong, because starting slightly conservatively saves glycogen and avoids the late slowdown that sinks many marathons.
Both work. Even splits are the simplest plan, and a mild negative split of 1–2% is usually the best strategy for recreational runners. Going out faster than goal pace in the first 10K is the most common cause of a painful final 10K.
A 4:00:00 marathon needs 5:41 per km (9:09 per mile). Even splits put you at the 10K mark at 56:53, the 21.1 km half-way point at 2:00:00 and 30K at 2:50:38. Enter 4:00:00 in the calculator for the full table.
Write the checkpoint times for 5K, 10K, half and 30K on your wrist or pace band, or set your watch to alert you at your target pace. Compare each checkpoint to your plan rather than checking pace every minute, since GPS pace jumps around.
Yes. The marathon is 42.195 km, so the final row of the table is a partial distance of 0.195 km (or 0.22 miles) at the same pace as the rest of that half.
