Ask ChatGPT to write you a 12-week cycling training plan and you'll get one in about 30 seconds. It'll look reasonable. It'll have periodization, recovery weeks, maybe even some interval prescriptions. And for someone with zero coaching, it's better than nothing.
But there's a canyon between "a plausible training plan" and "your training plan." And that canyon is exactly where CoachedBy lives.
What ChatGPT actually does
ChatGPT is a general-purpose language model. It's extraordinarily good at generating text that sounds like expert advice. When you ask it for a training plan, it draws on patterns from the millions of training articles, forum posts, and coaching resources in its training data.
The result is generic by definition. It doesn't know:
- Your current CP or W'
- How many hours you can actually train this week
- That you have a race in 6 weeks
- That you crashed last Tuesday and your left knee is swollen
- That your coach believes in polarized training, not sweet-spot
- What you did yesterday, or last week, or last month
It generates a plan that could work for a hypothetical average cyclist. That's not coaching — it's content generation.
What CoachedBy does differently
CoachedBy isn't a chatbot that happens to know about cycling. It's a coaching platform where AI is embedded into every layer of the coaching process.
Your data, not generic assumptions
CoachedBy connects to your training platforms — intervals.icu, and more coming. It sees your actual power data, your ride history, your fitness trends. When the AI builds a workout, the power targets come from your real power curve, updated continuously. Not from a guess based on "intermediate cyclist, 3-5 hours per week."
Your coach's methodology
Every coach on CoachedBy has their own AI — trained on their specific methodology, their workout library, their philosophy on periodization, intensity distribution, and recovery. When you chat with your AI coach, you're getting advice filtered through your coach's expertise, not a generic model's best guess.
A coach who believes in block periodization will give you a fundamentally different plan than one who favors traditional linear progression. ChatGPT doesn't know or care about this distinction. CoachedBy makes it the foundation.
Persistent memory
Ask ChatGPT for help on Monday, then again on Thursday — it has no memory of Monday's conversation (unless you manually provide context every time). CoachedBy maintains your full training history, conversation history, and athlete profile. The AI knows what plan you're following, what you completed, what you skipped, and what was modified.
This means the coaching evolves. It doesn't start from zero every time you open the chat.
Structured workout execution
ChatGPT gives you text: "Do 4x8 minutes at threshold with 4 minutes recovery." That's a description, not a workout. You still need to translate it into something your bike computer can execute.
CoachedBy generates structured workouts — precise intervals with power targets, durations, and cadence cues — and syncs them directly to your training platform. The workout shows up on your Garmin or Wahoo, ready to ride. No manual transcription, no guessing what "threshold" means in watts.
Real coaching behind the AI
The biggest difference: there's a real coach behind the AI. CoachedBy coaches set the methodology, review the AI's outputs, and are available for the human moments that no AI can handle. The AI scales their analytical work; the coach provides the judgment, empathy, and accountability.
ChatGPT has no coach. It has no accountability. It can't call you after a bad race or adjust your plan because it noticed you're stressed. It generates text and moves on.
The comparison table
| Feature | ChatGPT | CoachedBy |
|---|---|---|
| Generates training plans | Generic, based on description | Personalized, based on real data |
| Knows your power data | No | Yes, via platform sync |
| Follows a coaching methodology | No, uses general knowledge | Yes, coach-specific AI |
| Remembers your history | No (or limited) | Full conversation + training history |
| Creates structured workouts | Text only | Executable files synced to devices |
| Adapts to missed sessions | Only if you explain each time | Automatic, sees your calendar |
| Has a real coach behind it | No | Yes, every subscription |
| Costs | Free / $20/mo for GPT Plus | Varies by coach |
When ChatGPT is fine
Let's be fair: ChatGPT is useful for general training questions. "What is polarized training?" "How should I fuel a 4-hour ride?" "What's a good cadence for climbing?" These are knowledge questions, and ChatGPT answers them well.
It's also fine for inspiration — generating workout ideas, exploring training concepts, or getting a rough framework when you're self-coaching on a budget.
When you need more
But the moment you want training that's actually calibrated to you — your fitness, your schedule, your goals, your coach's philosophy — a general-purpose AI falls short. It doesn't have the data, doesn't have the context, and doesn't have the coaching relationship.
CoachedBy exists precisely in that gap: AI that's powerful enough to handle the analytical complexity of individualized coaching, but grounded in your real data and guided by a real coach's expertise. That's not something a chat prompt can replicate.
