AI Cycling Coach vs Human Coach: When Each One Makes Sense

Adaptive training apps can now build a plan, adjust it after every ride and predict how your fitness will move. For many riders that is a real step forward. But "AI coach" is a big word. As coaches, we use data every day – so here is our honest view of where AI helps, and where it doesn't.

What an AI coach does well

• Structure for little money. A sensible plan with progression, easy weeks and variety.
• Instant adjustments. Missed a session? Rode harder than planned? The plan adapts immediately.
• Data processing. It reads power, heart rate and training load faster and more consistently than any human.
• Indoor training. Combined with a smart trainer, it delivers precise sessions with no thinking required.
• Availability. Always there, at 5 am or 11 pm.

What an AI coach can't see

• Your life. It sees missed sessions, not why: a sick child, a deadline, a bad night, a divorce.
• Your technique. It can't see your position, your pedalling, your cornering or your fear of descending.
• Your body language. A coach notices the tired face at breakfast or the hesitation before a descent.
• Context. An AI sees the numbers of a race. It doesn't know you were in the wrong group, braked badly in two corners and didn't eat for an hour.
• Health warnings. Pain, illness, overtraining and low energy availability need a human conversation – and sometimes a doctor.
• Motivation and belief. Plans fail on motivation, not maths. A person who believes in you is hard to replace.
• Accuracy depends on input. Bad data (wrong FTP, no power meter, missing rides) means a confident but wrong plan.

Our view: sceptical, and here is why

"I'm very sceptical about AI training apps, because I know how little they are actually personalised," says our founder Darina Balabai. "Even if you enter all your data, the app can't see how you slept, what and how you ate, what mood you're in or how much you worked. It will never have enough data – and you will probably upload things you shouldn't. What you don't have is a person: feedback based on the real, practical experience of someone who works with athletes. Someone who understands the psychology, knows how to approach it, what to advise, how to support you, how to motivate you, how to improve your sleep."

That is the gap. An app can process your numbers. A coach works with you.

When an AI coach is enough

• You ride for fitness and want more structure than "just riding".
• You have no specific goal event, or a modest one.
• You train mostly indoors and have limited time.
• Your budget doesn't allow a coach right now.
• You are disciplined, honest with your data and listen to your body.

When you need a human coach

• You have an important goal: a qualifier, a World Championship, a first big race.
• You have stopped improving despite training consistently.
• You are coming back from injury, illness or a long break.
• You are new to the sport and need technique, group skills and safety.
• Your life is complicated and the plan needs judgement, not just maths.
• You race gravel or in the mountains, where skills decide as much as watts.

The best of both

The most effective approach for many amateurs is a hybrid:

1. A human sets the direction: testing, goals, season plan, technique, the big decisions.
2. Software handles the day-to-day: structured sessions, load tracking, small adjustments.
3. Regular human check-ins: monthly or after every block, to look at the data in context and change course.
4. Skills are learned in person: a camp or a few sessions with a coach on the road.

How we use data at Portcycling

We coach to real numbers – power, zones and power profile testing. Data is the starting point, not the coach. On our camps a coach rides with you, sees how you climb, descend and recover, and puts your numbers into context. After our Open The Season camp in Calpe you continue with 1 month of remote coaching – a human who knows your numbers and you.
