Runner's Splits — where it earns its place
On Runner's Splits —
You want to finish in under two hours; the question is what that means at kilometre one, when you feel immortal and are about to ruin everything. Runner's Splits does the pace arithmetic — target time into per-kilometre splits, or your pace into a projected finish — so the plan exists before the gun goes. … On this page: three concrete ways anyone who does this calculation more than once reaches for the Runner's Splits, and the signals that tell you it fits.
When the Runner's Splits earns its place
You come to the Runner's Splits the way you come to any well-made calculator: with numbers, a question, and no patience for a landing page. It gives you a result and forgets it. That is its whole personality.
Most tools in this category — web calculators festooned with ads, spreadsheet templates you paid for once and lost — solve a version of the same problem, then bill you monthly for the privilege of remembering it. The Runner's Splits takes the opposite bargain: one file, once, kept.
Three scenarios drawn from sport, fitness, and outdoors
The everyday one: you open the Runner's Splits on a Tuesday morning, punch in the numbers, and close it. Two minutes. The record is more honest than the app that pinged you to remind you.
The specific one: — the workflow it names is the calculation that most needs a home outside a subscription. Some people use only the Runner's Splits. Some fold it into a Swiss Knife next to five others. Both are correct.
The out-of-band one: months later, you want to look back. The Runner's Splits still opens because it is a file. There is no login lapsed, no export deadline missed. The answer is where you left it.
Signals it fits anyone who does this calculation more than once
You want a calculation that behaves like a document, not a service. You are comfortable typing your own numbers in. You would rather own the file than rent the calculator. Weight in the knife: 1. Manual: no manual — the tool is its own instructions.

Questions people ask
How do I calculate my race pace for a target finish time?
Give it the distance and the time you are aiming for, and it computes the pace and the splits. Write them on your hand, tape them to your bottle — the plan is now portable.
Is this a full replacement for web calculators festooned with ads?
For the working core of what most people use it for — yes. For enterprise features (team seats, integrations, auto-import), no. The Runner's Splits is deliberately smaller and more honest about its scope.
Who is the Runner's Splits not for?
Anyone who does this calculation more than once's opposite: a team that needs shared cloud state, or someone who wants automation over ownership. Use a SaaS for that; use this for the file.
A calculation that opens where you left it, on the machine you left it on.
