Is Whistle only for triathletes?

While designed with triathletes in mind, Whistle supports running, cycling, and swimming individually, and can be used by any endurance athlete.

How does the AI coach personalize my plan?

Whistle analyzes your health and workout data, along with your schedule, recovery, and weather, to create and adjust a training plan that fits your unique circumstances.

Can Whistle create structured workouts?

Yes, you can build custom structured sessions with blocks, steps, goals, and targets for running, cycling, swimming, and more.

Is my health data private?

Whistle only uses data needed for coaching tasks, processes temporarily in the cloud when required, and does not store long-term personal profiles.

Can I use Whistle without AI?

Whistle's core value is its AI coaching, but you can still plan and track workouts manually without relying on AI features.
