Run Pace Calculator vs Pace Calculator

PaceCalc is the pace calculator runners actually want to open. Pick any distance, set a goal time, get the exact pace and a full split schedule — then export a card worth posting. One tool. Three modes. Pick two, get the third. • PACE — set distance and target time, get your per-km or per-mile pace. • TIME — set distance and target pace, get your finish time. • DISTANCE — set time and pace, get how far you'll go. WHY RUNNERS USE PACECALC • Race-ready splits — even, negative, positive, or fully custom. Watch-ready. • 24 built-in distances — 5K, 10K, half marathon, marathon, ultras, track repeats and more. • Saved race plans with a real countdown to race day. • Lock Screen widget showing days until your next race. • Switch units anytime — kilometers, miles, or treadmill speed. • Siri and App Intents — "Calculate marathon pace for 3:30" just works. TRIATHLON PLANS Swim, bike and run legs, each in its own idiom: per-100 swim pace, bike speed in km/h or mph, run pace per km or mile. Sprint, Olympic, 70.3 and 140.6 presets, plus T1 and T2. Change your effort on one leg and the whole race re-times itself. SHARE CARDS BUILT TO BE POSTED Five layouts — Broadside, Terminal, Minimal, Pace Band, and a dedicated triathlon Story card. Drop your own photo behind any of them. Share your goal before the race. Afterwards, switch the same card to RESULT and show your actual finish against the plan. The Pace Band card is the one you tape to your wrist: checkpoint rows with cumulative elapsed time, rounded so it never drifts from your target. DESIGNED, NOT GENERATED Custom typography using Instrument Serif and JetBrains Mono. A signature colon accent on every pace and time. Paper-on-clay and ink-on-paper themes. No stock icons. No template UI. FREE. PRIVATE. NO ACCOUNT. • Free forever — no ads, no subscriptions, no in-app purchases. • No account, no sign-up, no email capture. Ever. • Every calculation runs on your device. The app works with no connection at all. • No personal data is collected. Anonymous crash and usage diagnostics only, never linked to you. Your race names and custom distances never leave your phone. BUILT FOR SERIOUS RUNNERS BQ chasers. Half and full marathoners. Track athletes running 400m repeats. Triathletes building a race plan leg by leg. Coaches writing plans for athletes. If you've ever opened a generic calculator app, given up, and done the pace math in your head — PaceCalc is for you. Made by a runner. Free forever.

Any two numbers, and the rest solves itself. Enter a distance and a goal time and you get the pace. Enter a pace and a distance and you get the finish time. Distance, time, pace and speed — give it any two and the other two fill in, in kilometres or miles. THEN IT HANDS YOU SOMETHING Most pace calculators show you a number and stop there. This one builds a race plan card: your goal, your pace, and a split table for every segment — laid out so you can send it to a training partner or keep it on your phone for race morning. WHAT'S INSIDE • Four-way solver: distance, time, pace, speed • 20 race distances from 400 m to 100K, each with a note on what it asks of you • Split tables in kilometres, miles, or track laps • Even, negative, positive and fast-finish pacing strategies • Equivalent times across distances, so a 10K result suggests a half marathon target HOW IT'S BUILT Distances are kept in metres and times in seconds. Everything else is derived from those two and rounded only when it is shown to you, so the numbers stay consistent between the solver, the splits and the card. • No account. Nothing to sign up for. • No paywall and no subscription. Every feature is free. • No data collected. Your saved plans never leave this iPhone. • Works completely offline, including in airplane mode on the start line. Equivalent times come from a standard endurance model (Riegel, 1977). They are estimates, not predictions. This app is a calculator and planning tool — it is not coaching, training prescription, or medical advice.
