    Your questions, answered ↓

    Your questions, answered first.

    What athletes who use AI Endurance ask us most.

    Will it keep up with my real week?

    Yes, every night.

    Your coach re-checks tomorrow against what you did, and moves or tunes sessions with the reason shown.

    Does it use my recovery data?

    Yes, every night.

    Your morning check-in, WHOOP or Oura, and your HRV against your own baseline all shape tomorrow.

    Can I ask why a session changed?

    Yes, any time.

    Every change carries one line on why, you can undo it, and you can ask your coach about it in chat.

    Can I train for more than one sport?

    Yes, six sports.

    Run, ride, swim, triathlon, HYROX and strength, on one plan that sees your whole week.

    What does it cost?

    $0, every feature.

    Fair-use limits on coach chat and form analysis keep it free for everyone.

    Do I get nutrition planning?

    AI Endurance has it.

    Nutrition planning is built in there. AthleteSpace has no dedicated nutrition module.
