Want to shake things up without changing the overall goal of your workout? For specific run types (like intervals, tempos, reps, and hills), you can instantly load a new variation of the session that provides the exact same training stimulus.
Open the run you want to modify.
Tap the Load new session icon in the action menu. (Note: This option is only available for specific run types).
A pop-up will appear with a summary of a brand-new workout structure (including the new intervals, distance, time, and pace).
If you like the new workout, tap Lock in this session. If you want to see a different variation, tap Load another session.
Your run will update immediately, while the rest of your training plan stays exactly the same.
(Tip: If you ever want to revert to the original workout, simply tap the Reset changes icon).
