Embed the race predictor

You can put the race-time predictor on your own running site. It runs the same prediction math as the home page, works on mobile, and keeps a runner on your page instead of sending them elsewhere. Free to use. The one condition is that the visible link back to racepredictor.run stays in place.

Paste this where you want the tool

<iframe src="https://racepredictor.run/embed/predictor"
  width="100%" height="760" style="border:0;max-width:640px"
  title="Race Time Predictor" loading="lazy"></iframe>

Sizing

The iframe runs full width up to 640px and stands 760px tall, which fits the predictor and its results without scrolling on most layouts. Change height if your theme needs it, and set max-width to match your content column.

Using it somewhere? Send the URL to hello@racepredictor.run and your page may get a link back from the blog.
