How to generate a running workout with AI
AI workout generation helps eligible paid users draft a structured running workout from a short prompt. The generated workout is a preview first, and you decide whether to accept it.
Write a useful prompt
Describe the type of running workout you want, such as easy running, threshold intervals, kilometre repeats, strides, or a long-run structure.
Include practical details like total duration, work and recovery lengths, distance targets, and preferred pace guidance where relevant.
Review before accepting
RunSync shows the generated workout as an unsaved preview with sections, durations, and pace targets where available.
AI-generated workouts can be wrong. Review the structure and intensity before accepting the preview.
Accepting the preview only loads it into Run Builder. Saving, scheduling, and Garmin sync remain separate actions that you choose afterwards.
Quota and availability
AI workout generation has a monthly quota by plan and the remaining count is shown in RunSync when the feature is available.
A successful preview consumes quota. Provider timeouts, provider failures, invalid output, and validation failures do not consume quota because no usable preview was delivered.
If generation is unavailable, try again later or build the workout manually in Run Builder.
