Embeddable running tools

Useful calculators for running sites, clubs, and coaches.

Add a Treadly tool to a race guide, club page, newsletter, or coaching resource. Each widget stays compact, links back to the full tool, and keeps the calculator itself free for runners.

Embed notes

Widgets are noindex and point canonical traffic back to the full Treadly tool pages. They do not collect personal health data or require sign-in.

For a fixed-height fallback, use an iframe directly:<iframe src="https://treadly.run/embed/heat-pace-adjustment-calculator"></iframe>
