Build Your Own Adaptive AI Coach With Claude or ChatGPT

Your plan looked perfect on Friday. Then Saturday’s easy ride turned into a hard group ride, Sunday’s long run felt heavy, and a work trip took Wednesday. You don’t need a new sixteen-week plan. You need someone to look at the week you actually had and help you decide what happens next.

That is what an adaptive coach does. With TrainingDojo connected, Claude or ChatGPT can do it too: read your TrainingPeaks or Intervals.icu calendar, talk it through with you, and put the changes you agree on straight onto your calendar.

What it looks like

You ask a question about your training in plain language. Your AI reads the relevant workouts itself, so you don’t paste anything in. Then it answers like a coach who has seen your week.

Three things make this different from asking a chatbot for a workout. It starts from what you actually did, not from a template. It can tell you to change nothing. And when you say yes, the finished workout is on your calendar, with intervals and targets, ready to sync to your watch.

Start with this week, not the whole season

Your first question should be small enough that you can judge the answer. Pick a recent session and the next workout. If you keep more than one calendar, say which one to use.

Review my last three days in TrainingPeaks against what was planned.
I felt flat on Sunday and only have 45 minutes tomorrow.
Should tomorrow's workout change? Tell me what you'd do and why.

Read the answer the way you would read a coach’s note. Does it mention the right sessions? Does the reasoning make sense? If something is off, say so. “The group ride was planned” or “I slept fine” is exactly the context that improves the next answer.

Make it a weekly habit

Adaptive coaching works best as a rhythm: look back, add what the data can’t show, decide on the next step. Put your goal race, usual training days, and preferences in your AI app’s instructions or project so every conversation starts with them. Your AI reads fresh training data each time you ask.

You can also schedule it. A weekly review can be waiting for you every Sunday evening, so the conversation starts with a summary instead of a blank page.

From conversation to calendar

This is where TrainingDojo earns its place. Once you agree on a change, your AI can:

• move a workout to another day
• shorten it or rewrite its description
• build a new structured workout with warm-up, intervals, recoveries, and targets
• reuse a favorite session from your Workout Vault
• build and publish a whole new training block

You see the change before it happens. TrainingDojo tells your AI to show you what will change and wait for your OK, and Claude and ChatGPT ask your permission before running a tool that writes to your calendar. Workouts land in TrainingPeaks or Intervals.icu, or go straight to Garmin Connect or Wahoo. Zwift gets a workout file.

Bring the context your watch can’t record

Sleep and HRV help when you record them, but a stressful week, sore legs, or a session that felt surprisingly easy matter just as much. Say it in a sentence. The recovery guide shows how to combine the numbers with how you feel. If typing it all out is a chore, you can talk it through by voice instead.

Pick your sport

• Running: heavy long runs, missed tempo sessions, and race goals.
• Cycling: group rides, interval execution, and short-on-time days.
• Triathlon: three sports, pool hours, and one week to fit them into.

Try it on one real question

You can connect your AI for free. Free reads all your training data and includes three workout publishes. Pro or Coach adds bulk publishing and ongoing calendar management. TrainingDojo runs on your own Claude or ChatGPT account, so it uses no TrainingDojo AI credits.

Follow the setup guide, then ask about one recent workout and the next one. If the answer sounds like it came from someone who looked at your week, you have an adaptive coach.
