Pace, Time & Distance

“I ran 10k in 58 minutes — what pace is that?”

Ran 10k in 58 minutes and want the pace? Want to know what a two-hour half marathon means per mile? Fill in any two of the three, leave the last one empty, and it works itself out — then gives you every split.

  • Fill in two, the third fills itself in
  • Type 58, 58:20 or 1:24:30 — no converting to seconds
  • Every split plus the halfway time, ready to print
  • The answer in miles and kilometres at the same time
  • What the same pace gives you over 5K, 10K, half and full

How it works

Three steps, then you're done

Fill in two

Distance, time or pace. Leave the one you want blank.

Read the third

Shown in miles and kilometres both.

Take the splits

What the watch should say at every mile.

Nothing you type ever leaves your computer. There is no account, no login and no server. Switch your wi-fi off and it still works — that's not a promise about our policy, it's just how the tool is built.

Questions

Do I need to install anything?

No. Each tool is a single file. Double-click it and it opens in Chrome, Edge, Safari or Firefox — whichever you already have. No account, no password, no software.

Does anything get uploaded?

No. Your numbers and files never leave your computer — the tools have no way to send them and no internet connection is needed to run them. You can switch your wi-fi off and they still work.

I'm not good with computers. Is this too hard?

The first thing every tool does is walk you through it in five short screens with pictures. Then there's a button that fills it with example numbers so you can watch it work before touching anything.

Will it work on my phone?

Yes. Email yourself the file and open the attachment, or drop the files in iCloud Drive, Dropbox or Google Drive and open them from there — then they're on every device you own.
