What athletes say

“It flagged my HRV dropping for 3 days and swapped my intervals for easy mileage. Turns out I was getting sick. Saved two weeks of training before my half marathon.”
Michael Soumbatov
Runner · sub-1:30 half

“athletedata is exactly what I've subconsciously needed. It has the potential to be a game changer for endurance sports.”

Scott Poteet
Polaris Dawn pilot · 4x Kona finisher

“I'm a triathlon coach myself and was pessimistic to begin with - I'd tried the other AI coaching tools and didn't enjoy them. This is much more realistic. A really great tool, and I'm surprisingly enjoying it.”

Jason Pretty
Triathlon coach

“It's reignited my enjoyment around training and helped me execute sessions better - training, recovery, nutrition and more. I've had a number of coaches, and this is actually better.”

Adam York
Triathlete · HYROX

“It's made clear the kind of progress I need to sustain to reach my A race this year, and explains the numbers Training Peaks and Garmin throw at me. A perfect complement to my IRL coach - I would never have said that before trying it.”

Sharon McNary
Ironman World Championship finisher

“Caught my easy pace drifting 15 sec/km over two weeks. Used to take me weeks to notice.”

Berke Aymergen
100mi finisher

“Moved leg day when it saw I had a tempo the next morning. No other app does this.”

3 days of HRV decline + 4h sleep debt. I reworked tomorrow: your 5×1k threshold became an easy Z2 spin, and moved the long run to Sunday. You're absorbing more load than you're used to - back off now and it pays off race week.7:12 AM
Makes sense, legs are wrecked. Thanks7:13 AM
Done - plan updated and synced to your calendar. That's −47 TSS this week.7:13 AM

Pushed to your watch

The adapted session - structured intervals and all - lands straight on your Garmin or COROS, ready to start. No manual entry, no fiddling with workout builders.

The connective tissue your stack has always been missing.

Endurance athletes run 4-6 apps. They don't talk. Your coach shouldn't have to squint at six screenshots, so we built the layer that does.

Questions, answered.

Why not just use ChatGPT?+
Three things ChatGPT can't do:

1. See your data. We run a real data pipeline with direct API integrations to 19 training, recovery and nutrition apps, so your coach reads your actual numbers in real time. No screenshots, no copy-paste.

2. Reach out first. Your coach messages you proactively after every workout and sleep, and flags HRV drops, pace drift or volume spikes before you notice them.

3. Manage your plan. An auto-adapting 14-day training plan that rewrites itself when you skip a session, sleep badly, or your CTL drifts off track. Tomorrow's workout lands on your watch, ready to start.

Plus persistent memory: your athlete profile, race goals and history compound across every conversation. ChatGPT forgets the moment you close the tab.
Is the coaching evidence-based?+
Yes. The coach reads from a curated training-science reference library before prescribing zones, structuring blocks, or quoting a target pace. Not generic LLM knowledge - anchored in published methodology: Seiler's polarized 80/20 distribution, Jack Daniels' VDOT system, Ingebrigtsen-style Norwegian double-threshold, marathon periodization and taper protocols, in-race fueling research (60-120 g/h carb intake), running power zones, swim frequency rules, female-athlete physiology and cycle-phase considerations, detraining and return-to-training protocols, and qualifier standards for Boston, the WMM, UTMB and Ironman.

When you ask "what should my long run pace be?" or "how should I taper for Berlin?", the coach pulls the relevant reference, then applies it to your numbers - your recent CTL, your typical paces, your race date, your weekly volume. The answer is grounded in the file, not improvised, and methodology gets cited by name (Seiler, Daniels, Friel, Ingebrigtsen) when it sharpens the explanation.
What's the difference between Coaching and MCP-only?+
MCP-only ($9/mo) lets you 'chat with your data' using your own Claude / ChatGPT / Cursor. No WhatsApp/Telegram proactive coach. No AI-managed training plan.

Coaching ($25/mo) is the full product: a proactive AI coach that messages you in Telegram or WhatsApp after every workout and sleep, an auto-adapting 14-day training plan, and full MCP access included.

Pick MCP-only if you already have an AI you trust. Pick Coaching if you want a coach that reaches out first. See the MCP plan →
How does it compare to a real human coach?+
It's complementary, not a replacement. A great human coach is irreplaceable for race strategy, mindset, and the human element of pushing you through a bad block.

What we replace is the daily data work most coaches don't have time for - reading your HRV, sleep, pace, power and lifts every day, flagging drift before it becomes a problem, and rewriting your plan when life happens. Most human coaches see your data once a week. Your AI coach sees it within minutes of every workout, every sleep, every recovery reading.

Athletes with human coaches use us for the day-to-day vigilance their coach can't do at $300/month. Athletes without coaches use us as their primary coach.
Is athletedata.health free?+
You can connect all your apps and get to know your coach for free. After that, every plan starts with a 7-day free trial. Cancel anytime, 30-day money-back guarantee.
What data do you store?+
We store OAuth tokens to connect to your fitness apps, your conversation history with the coach, and an evolving athlete profile. We do not store bulk copies of your workout or health data. Your coach queries it in real time via the integration APIs. We never sell your data, never use it to train AI models.
Will the workouts show up on my watch?+
Yes. Structured intervals from your 14-day plan flow into Garmin Connect or COROS as scheduled workouts, ready for the watch. Warmup, work blocks, cooldown. The watch reads each segment as you go.
Which apps do you support today?+
Activity, power & training: Strava, Garmin, Wahoo, Polar, COROS, Suunto, Zwift, TrainerRoad, Intervals.icu, TrainingPeaks. Recovery & sleep: WHOOP, Oura, Apple Health, Withings. Strength: Hevy. Nutrition: Cronometer, MyFitnessPal. Cycle tracking: Clue, Flo. Scheduling & docs: Google Calendar, Google Sheets, iCal. 21 apps today, and we ship new ones within days when athletes ask.
Can I cancel anytime?+
Yes. You can cancel your subscription at any time and continue using the service until the end of your billing period.

“YouTube got me to my first triathlon. A real coach got me to my second. Then the bill arrived. Static plans were the fallback, but the moment life got in the way, I was on my own. That's the gap we're closing.”

Training around a job, a family, a life? Same. Message me - I want to hear what's breaking.
