METHODOLOGY

How this calculator works

  1. Galloway run-walk-run method

    Alternating run intervals with planned walk breaks reduces injury risk and lets many runners finish marathons faster than they could running continuously. PaceCalc surfaces the average pace and total finish time given a run/walk ratio.

    Jeff Galloway, Galloway Training Programs, since 1973. Empirical method used by hundreds of thousands of marathon finishers.

FAQ

Frequently asked

What is the Galloway run/walk method?
Jeff Galloway's method uses planned walk breaks during running to reduce fatigue and injury risk. Common ratios include 4:1 (run 4 min, walk 1 min), 3:1, and 2:1. Many runners achieve PRs using this strategy.
What run/walk ratio should I use?
Beginners often start with 1:1 or 2:1. Intermediate runners use 3:1 or 4:1. The best ratio depends on your fitness level and race distance. Experiment in training to find what feels sustainable.
Is run/walk slower than continuous running?
Not necessarily! Walk breaks reduce fatigue, which can help you maintain a faster run pace. Many runners find their effective pace with run/walk is similar to or faster than their steady-state pace, especially in longer races.
When should I take walk breaks?
Start walk breaks from the very beginning — don't wait until you're tired. Consistent, planned walk breaks from mile 1 are far more effective than crisis walks later in the race.
Can experienced runners benefit from run/walk?
Yes! Run/walk isn't just for beginners. Many experienced marathon runners use 4:1 or 5:1 ratios to manage fatigue, especially in hot conditions or on hilly courses. It's a smart racing strategy at any level.
