Try the Race Time Predictor first, then come back to generate your split chart. You can also use the Running Split Calculator for any other race distance.
The marathon is 26.2188 miles, and pacing it correctly is one of the most important factors in performance. The golden rule: start conservative, finish strong. Your pace in miles 1–3 should feel almost embarrassingly easy — if it doesn't, you've gone out too fast.
Use your average pace per mile (shown above) as your target for every mile. Program it into your GPS watch as a pace alert so you get a notification if you drift more than 10–15 seconds per mile off target.
Halfway (13.1 miles) is an important checkpoint. If you've run the first half in your target half-marathon split, you're on track. If you've run it 2+ minutes faster than planned, prepare for a tough second half.

A negative split means running the second half of the marathon faster than the first. It's the pacing strategy used by most world record performances and is highly recommended for runners who want to maximize their potential.
In practice, a 1–2% negative split means running the second 13.1 miles about 1–2 minutes faster than the first. For a 4:00 marathon, that might mean running the first half in 2:02 and the second in 1:58.
The key to a negative split is the first 10 miles feeling controlled and easy. If you feel good at mile 18–20, you have permission to push. If you feel rough by mile 16, hold your pace and don't panic — just stay consistent.
Miles 18–22 are often called "the wall." Glycogen depletion and accumulated fatigue converge. Having a well-practiced pace chart — and sticking to it in the first half — is the best way to have something left in the tank when it matters most.
