Pace Calculator

Runner enters a recent race time, gets their training paces and equivalent race times instantly. Auto-resizes to fit its content.

<iframe

  style="width:100%; border:none;"
  id="prnerd-pace-calculator"
></iframe>
<script src="https://pr-nerd.run/embed-loader.js" async></script>

Pace Chart

A quick-reference finish-time table by pace for 5K, 10K, half, and full. Works great at a fixed height with its own scrollbar.

A note on sizing

The Pace Calculator's height changes as someone fills it in, so it uses the small loader script above to auto-resize the iframe to fit. The Pace Chart has a fixed-height table with its own internal scrollbar, so it works fine as a plain iframe — no script needed. Feel free to adjust the height value to whatever fits your page.

Or just link to us

Prefer a link over an embed?

A plain link works great too — on a resources page, in a pre-race email, wherever makes sense. It's also the simplest way to point runners to anything else we offer beyond the two widgets above.
