Describe it or paste a screenshot, and it's ready in seconds. Then just run: voice and haptic cues guide every interval, even with your screen off. 25 workouts runners actually love — HIIT, fartlek, tempo, hills, Yasso 800s. On iPhone and Apple Watch. Because running the same pace every day only makes you better at running the same pace. Break the plateau. EVERY RUN IS A NEW CHALLENGE Every workout here has a specific goal and a different feel — so you actually train different muscles, systems, and skills instead of just logging miles.

Paste a screenshot of a workout you saw online and we'll convert it into intervals. TRAIN BY EFFORT, NOT NUMBERS Every interval shows a target effort (80% for work, 30% for recovery).
