Immediate Post Run Feedback

Every run triggers personalized analysis based on your goals and fitness history. NXT AI tells you what went well, flags what to watch, and adjusts upcoming workouts automatically.

Should I still do my speed workout tomorrow? My legs feel heavy from yesterday's long run.
NXT AI Based on your 16-mile long run yesterday and elevated HR data, I'd recommend swapping tomorrow's intervals for an easy 5-miler. I've moved your speed session to Thursday when you'll be more recovered.
Can you also adjust my pace targets? I think I'm ready to push a bit harder.
NXT AI Your last 3 tempo runs show a 12-second pace improvement. Updating your target paces across all workouts now.

On Demand Coaching

Ask NXT AI to reschedule a run, adjust your paces, or plan a race strategy — and it does it, using everything it knows about your running. Like texting a coach who has your full training history.
