How to use a pace chart
A marathon pace chart assumes even pacing — the same effort start to finish — and shows the exact clock time you should hit at every major checkpoint if you're on goal. Write the key splits (10K, half, 20 mile) on your arm or set them as alerts, so you know by halfway whether you're on track without doing math mid-race.
Even pacing vs. a slight negative split
This chart shows dead-even pacing. Most experienced marathoners actually run a slight negative split — a few seconds per mile conservative early, a bit faster late — since the back half of a marathon is where even-paced runners tend to fade. Use the Split Calculator if you want that shape built in.
