the short answer
How to become a running coach: earn a recognized running-specific certification, learn to program mileage and intensity safely (zones, paces, periodization toward a race), and hold a clear scope line - you coach training, not injuries. Then build the business: a niche, an offer, pricing, and a way to deliver programs and check-ins online. The sport is remote-friendly, so most of your coaching happens through an app, run logging, and wearable data on a weekly review. This is general information, not professional or medical advice; certification requirements vary by country.
