Run/Walk & Pace Calculator

Calculate run/walk interval paces or plan any race with pace, speed & splits — miles or km. Dark & light theme. No ads, no account required.

Two calculators. One app. Built for runners who race smart.

RUN/WALK INTERVALS

The Galloway Method and other run/walk strategies are proven ways to run farther, finish faster, and recover better on race day. But the math is tricky — you need to know your exact run pace and walk pace to hit a target finish time.

Run/Walk & Pace Calculator does that math instantly.

Enter your target finish time, your run and walk interval durations, and one known pace. The app solves for the missing pace in seconds.

• Solve for run pace or walk pace • Any interval combination — 4:00/1:00, 3:00/1:00, 1:00/1:00, and beyond • Presets: 5K, 10K, Half Marathon, Full Marathon • Miles or kilometers

PACE CALCULATOR

Enter any two of distance, time, pace, or speed — the app calculates the rest and shows you a complete split-by-split breakdown to the finish line.

Targeting a 1:45 half marathon? Enter the distance and time and instantly see your required pace, speed, and every split from the gun to the tape.

• Solve any combination: distance + time, pace + distance, time + speed • Per-field unit toggles — mix miles and km freely on the same screen • Adjustable split interval, defaults to 1 mile or 1 km • Partial final split shown automatically when distance isn't a whole multiple • Presets: 5K, 10K, Half Marathon, Full Marathon

BUILT FOR RACE DAY

Races happen in places with bad signal — corrals, trails, remote start lines. Run/Walk & Pace Calculator works entirely offline. No server, no login, no waiting.

The custom on-screen keypad keeps entry fast and precise. Tap any field to activate it, tap Done to dismiss and see your full splits table unobstructed.

Dark and light themes follow your iPhone's system appearance automatically.

• Fully offline — no signal needed • Custom keypad with one-tap dismiss • Dark and light mode • No ads • No account or login required • No data collected or transmitted

WHO IT'S FOR

• Galloway Method runners planning run/walk intervals • Marathon and half marathon runners targeting a specific finish time • Runners converting between miles and kilometers • Coaches building pace plans for athletes • Anyone who wants to know: "If I run this pace, when do I finish?"
