Running Pace Calculator Splits vs Run Pace Calculator & Splits

PREMIUM — PURCHASE REQUIRED: All features described below are part of Pro and require a purchase: a weekly or yearly auto-renewing subscription, or a one-time lifetime purchase. You don't need another app to record your runs. You need the math right: the exact pace that gets you across the line at your goal time, the splits that get you there without blowing up in the final third, and an honest prediction of what you can actually run. RunSplit is that calculator — built for the week before the race, not the race itself. No tracking, no sensors, no watch required. Type your numbers, get your answers, write them on your arm. WHAT YOU GET • Solve any two of pace, time and distance for the third — a 3:49 marathon becomes 5:26/km or 8:45/mi in two taps, with km/h and mph alongside. • A full split table for your goal time: every kilometre or mile with its pace and elapsed time, so you know 10K in should read 49:40 — and whether you're ahead of yourself. • A negative-split slider: start a few percent easier, finish faster, and see the whole fade charted before you commit to it on race day. • Race predictions from a result you've already run — enter your 22:30 5K and Riegel's endurance formula projects your 10K, half and full marathon. • Six training pace zones from your threshold pace, following the intensity tiers in Jack Daniels' Running Formula — recovery through repetition, in your units. • Treadmill incline converted to equivalent flat-ground pace, so 5:00/km at 4% grade finally gets the credit it deserves. Save your race plan — distance, goal, splits and all — and reopen it any time before the gun goes off. PERFECT FOR • The marathoner deciding, two weeks out, whether the goal is 3:59 or reality • Half-marathon runners chasing a personal best with an even or negative split • Coaches who write splits for athletes and are tired of spreadsheets • Treadmill runners keeping winter workouts honest at real outdoor effort WHY NOT JUST A TRACKING APP? Trackers tell you what you ran after it's over. RunSplit answers the question you actually have beforehand: what should the clock read at every marker if today goes right? It's the difference between reviewing a race and planning one — and planning is where the PB is made. PRIVATE BY DEFAULT Everything is computed on your iPhone. No account, no sign-up, and your saved race plans never leave the device. PREMIUM (PURCHASE REQUIRED) RunSplit Pro unlocks the race-time predictor, training pace zones, the treadmill converter, negative-split planning and unlimited saved plans. Choose a weekly or yearly subscription, or a one-time lifetime purchase — every option unlocks everything. Pick your race, set your goal, and walk to the start line already knowing every split.
