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.
