True Pace: Running Calculator

Most pace calculators assume you’ll run the same pace for the entire race. Real races rarely work that way.

True Pace helps you build a race plan with paces that can vary by mile or kilometer, so you can see how hills, fueling, fatigue, strategy, and late-race surges affect your finish time.

Completely redesigned from scratch, True Pace now works beautifully on iPhone and iPad, with a cleaner planning flow, interactive pace graphs, race notes, PDF export, printing, and sharing with other True Pace users.

With True Pace you can:

• Plan even, positive, or negative split pacing strategies • Adjust individual miles or kilometers • Compare different race plans without starting over • Account for hills, water stops, fueling, and key course landmarks • See your pacing plan visually with an interactive Paceline graph • Add notes to any split • Export or print race plans as PDFs • Share saved races with friends, coaches, or other True Pace users • Plan common race distances including 5K, 10K, 10 mile, half marathon, marathon, and custom distances

Pacing Strategies

True Pace makes it easy to test different ways to run the same race. Want to know what happens if you run steady through mile 20, then pick up the pace for the final 10K? Want to compare that against starting more conservatively and getting faster every few miles? True Pace lets you build, duplicate, and adjust those plans with very little data entry.

Paceline

The Paceline graph gives you a quick visual view of how your pace changes over the course of the race. Swipe across the graph to inspect individual splits and understand exactly where your plan gets faster, slower, or stays steady.

Race Notes

Add notes to any mile or kilometer so your plan includes more than numbers. Mark climbs, turns, water stops, gels, landmarks, or reminders for the moments you know will matter.

Sharing and Printing

Saved races can be shared with other True Pace users, sent to friends or coaches, exported as PDFs, or printed for race day.

True Pace was built by an independent runner who wanted a better way to plan races than spreadsheets and generic calculators. You can use the app for free, with a one-time purchase available if you want to save unlimited races.
