Run Pace Calculator vs Run Pace Calculator & Splits

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.

Need your running pace in seconds? Enter any two of pace, time, or distance and PaceCalc instantly solves the third — in kilometers or miles, with speed shown in both km/h and mph. No guessing, no spreadsheet math. Most pace tools stop at one number. PaceCalc goes further: it forecasts every race distance from a single result, builds a segment-by-segment split plan for race day, and keeps a history of every calculation you save — so the number you need is always one tap away.
