AI coach or human coach?
A human coach costs from about $39 to $400 a month for running, more for triathlon. An AI coach can cost nothing. Here is what each one does better.
No account, no card.
The short answer
A good human coach knows you as a person and is worth it if you can budget $100 to $400 a month and want that relationship. An AI coach adapts every day, answers at any hour and can be free. Athlete Space is a free AI coach that rewrites your plan every night from your training and recovery and explains every change in chat. Many athletes use an AI coach until a big goal makes a human coach worth the money.

Where AI wins and where a person wins
AI adapts every night, never misses a check-in and costs little or nothing. A person brings judgement about you that no data shows: your life, your nerves, your history. The right choice depends on your budget and on how much that relationship matters to you.
