Run Walk Pace Calculator — Average Pace With Intervals

Blend run and walk intervals into an average pace per mile/km, plus finish times for 5K, 10K, half and full marathon.

—

Formula

Average pace = total interval time ÷ distance covered in one interval = (run sec + walk sec) ÷ (run sec/run pace + walk sec/walk pace). Distance in the interval is measured in miles, so paces stay in min/mile.

Frequently Asked Questions

Does run-walk really work for marathons?

Yes — the Galloway run-walk-run method has taken hundreds of thousands of runners to marathon finishes. Scheduled walk breaks reduce muscle fatigue and slow the late-race pace drop, so many runners finish faster overall than with continuous running.

What interval should a beginner use?

Common starting points are 30s run / 30s walk or 60s run / 30s walk. As fitness grows, lengthen the run segment (2–4 min run / 30s walk) rather than speeding up the walk.

How fast should the walk segment be?

A purposeful 15–16 min/mile brisk walk. The walk is recovery, not a stroll — keep cadence up and you lose far less average pace than expected.
