Marathon Pace Calculator — FAQs

What pace for a sub-4 marathon?

5:41/km (9:09/mi) — with even splits. Most plans bank a little early pace; blowing up at 30km is the classic failure mode.

Negative splits worth it?

Yes — the second half costs more pace per effort. Running the first 5km slightly below goal pace is the usual winning pattern.
