Running Calculator Widgets for Blogs

Make running articles more useful without burying readers in math

RunCalc widgets help running blogs turn advice into action. A pacing article can include a pace calculator, a marathon guide can include a marathon pace widget, and a race-preview post can include a race predictor.

The widget should support the article, not replace it. Keep the attribution visible and link readers to the full RunCalc calculator when they need the complete decision system.

Best blog placements

• Running Pace Calculator inside pacing and training-plan articles.
• Marathon Pace Calculator in marathon goal, taper, and race-week guides.
• Half Marathon Pace Calculator in half-marathon strategy posts.
• Race Time Predictor in posts about realistic goals and recent race evidence.

Script snippet

<div class="runcalc-widget" data-calculator="pace-calculator"></div>
<script src="https://running-calculator.com/embed.js" async></script>

The script version is the simplest option when a blog template changes iframe heights across devices.

Why this helps readers

• They can test a goal without leaving the article immediately.
• They can open the canonical calculator page for more context and saving.
• The visible attribution makes the source transparent instead of hiding links.
