What this result means
Pace bands are what people tape to a wrist or print on a bib. This generator always uses the official marathon distance. You get a kilometre column and a mile column. Even is the default. A 2% negative profile uses the same half-and-half engine as the negative-split calculator.
The marathon pace calculator already shows a shorter split summary. This page is the full band. The mile split and kilometre split tools leave distance free; here the distance is 42.195 km.
A 4:00:00 even band is about 5:41/km. 10 km is 56:51, halfway 2:00:00, 30 km 2:50:34, finish 4:00:00. Mile 13 is near 1:59 on a 26.2 mile even plan because 13.1 miles is halfway, not 13.
A 3:00:00 even band is about 4:16/km or 6:52/mile. The 2% negative option makes the first half slower than 1:30 and the second half faster, still summing to 3:00:00.
Calculation method
Even bands use constant pace: time × (marker ÷ 42.195). The 2% negative option uses first-half time = total ÷ 1.98 and a faster second-half pace after 21.0975 km. Mile markers use 1.609344 km per mile.
Exact arithmetic on 42.195 km. Displayed times round to the nearest second.
Bands do not include aid-station standing time, hills, or a 4:15 pacer who is not 4:00. Print the table; still run the first 10K with judgement.
Frequently asked questions
What pace is a 4-hour marathon band?
About 5:41 per kilometre and 9:09 per mile even. Enter 4:00:00 for every km and mile row.
What does 2% negative mean on the band?
The second half is 2% faster in time than the first. Halfway is later than 2:00 on a 4-hour goal. The finish is still 4:00:00.
Is this a 42 km band or 42.195?
42.195 kilometres, the official marathon. 42 km even splits would finish about 55 seconds early at 4:00 pace.
Can I get only miles?
This page prints both. For mile-only on a custom distance, use the mile split calculator.
