Running Calculator Widgets for Coaches

Help athletes turn goals into race decisions

RunCalc widgets let coaches add practical calculators to training notes, team resources, and athlete portals without building calculator logic from scratch. The full RunCalc pages remain the canonical destination for deeper explanations, methodology, and saved race plans.

Attribution must stay visible. Place the “Powered by RunCalc” link next to the embed so athletes can verify the source and open the complete calculator.

Four widgets to start with

• Running Pace Calculator for translating workouts and race goals into required pace.
• Marathon Pace Calculator for 26.2-mile pacing and 30K risk-point planning.
• Half Marathon Pace Calculator for 13.1-mile pacing and 15K decision planning.
• Race Time Predictor for sanity-checking goals from recent race evidence.

Script snippet

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

The script version auto-sizes the iframe and adds the visible attribution link. Use it when your site layout changes across desktop and mobile.

Coach use cases

• Pre-race emails where athletes need a realistic A/B/C pacing target.
• Training-plan libraries where runners convert goal time to workout pace.
• Team pages where athletes compare recent race evidence with future goals.
