STAS knowledge base

Athlete profile

Your STAS profile is where you keep the facts your AI coach should not have to ask for every time: body metrics, heart-rate references, personal bests, training background and the other sports you do.

Workout data shows what happened. Your profile helps explain who it happened to. Together, they give ChatGPT or Claude a much clearer starting point for analysis, planning and adjusting training.

What the profile is

The profile is the stable part of your training context.

Long-term context, not a training plan

Your profile is not a weekly plan and not a workout calendar. It describes the athlete: height, weight, heart-rate anchors, training history, best results, other sports and useful background.

These details do not change after every workout, but they affect almost every coaching decision: load, intensity, recovery, pacing and risk. That is why STAS keeps the profile separate from goals, training rules and the calendar plan.

Why STAS stores it separately

Important coaching context should not depend on chat memory.

STAS keeps your profile, goals and training rules in a structured context layer outside the conversation. When you ask for a workout review or a plan, ChatGPT or Claude receives this context together with your training data.

That is more reliable than repeating the same background in every chat. A long conversation can lose focus; the profile stays available between sessions and gives the AI a consistent base to work from.

What belongs in the profile

The profile has a clear structure. STAS knows which fields it can use and can show what is still missing.

Main fields

A typical profile can include:

birth year and sex;
height and weight;
maximum heart rate and threshold heart rate;
resting heart rate and MAF heart rate as useful zone references;
personal bests and race results, such as a 10K time;
other sports and important training background;
current training phase, such as base training, race preparation or recovery;
extra notes that help a coach understand your situation.

Why it matters

Your watch gives STAS the training file. The profile gives the training file context.

The missing layer behind the numbers

The same workout can mean different things for different athletes. A 60-minute run, a high heart rate or a 10K result cannot be interpreted well without knowing the athlete’s background.

The profile helps the AI understand your level, your reference points and the kind of training that is realistic for you. It makes the advice less generic and reduces the need to guess.

How to fill it in

You can update the profile on the website or through the AI.

On the website

Open your profile on stas.run and add the fields that matter most for training: heart-rate references, current level, best results and useful background. You do not need to complete everything at once. Even a few reliable fields already make the AI context better.

“Remember my height, weight and 10K personal best.”

You can also ask the AI to update your profile in chat. STAS will prepare the change, show you exactly what would be saved and wait for your confirmation. After that, the same information appears in your profile on the website.

How the AI uses it

The profile becomes part of the STAS context summary.

Profile inside the full coaching context

When you ask for analysis or planning, the AI sees your profile together with your goals, training rules, current condition, completed workouts and planned sessions.

That helps it understand your training as a whole instead of treating each workout as an isolated file. If some profile fields are empty, STAS does not invent them. The AI can still work with the data that exists and may ask for a missing detail only when it would improve the answer.

Limits

The profile improves coaching context, but it does not replace judgment.

Important boundaries

The profile is coaching context, not a medical record.
STAS does not invent missing profile data.
Sensitive details, such as weight, are used only when they are relevant to the task.
Very long profile notes are better split into clear, useful pieces.
The final training decision is still yours. The profile informs the answer; it does not make decisions for you.

The profile is not the plan

The profile describes you. It does not decide what you should do next week. For planning, STAS also uses your goals, rules, current condition and calendar.

Frequently asked questions

Short answers about the athlete profile in STAS.

How is the profile different from goals and rules?

The profile describes the athlete: body metrics, heart-rate references, background and results. Goals describe what you are preparing for. Rules describe how training should fit your life. In simple terms: the profile says who you are, goals say where you are going, and rules say what constraints the plan must respect.

Do I have to fill in every field?

No. Start with the fields that affect training decisions most: heart-rate references, current level, key results and important background. You can add the rest later.

Can the AI change my profile automatically?

No. The AI can prepare a profile update and show it to you, but STAS saves it only after you confirm. The same principle applies to goals and training rules.

Why add resting heart rate and MAF heart rate?

They can be useful references for heart-rate zones and easy-intensity control. They help the AI choose more realistic ranges and interpret whether a session fits your usual training context.

Do personal bests affect pace guidance?

Yes. STAS can use race results and personal bests to understand your level and estimate training references, such as VDOT and pace ranges, when the data supports it.

Can I see the profile outside the chat?

Yes. The profile is available in your personal account on stas.run. You can edit it there, and STAS also includes it in the context summary sent to ChatGPT or Claude.
