Today
WHOOP recovery 31%, Garmin Body Battery at 12. Your run volume jumped 40% this block and HRV has been dropping for 3 days. Swapped today's intervals for an easy 30-min jog.7:12 AM
Makes sense. Legs are cooked from yesterday7:14 AM
That's what your Garmin training load says too. Moved your tempo run to Thursday, updated your calendar.7:14 AM
After your run
Strava logged 14km at 5:12/km avg - your pace drifted 15 sec/km faster than prescribed. Fatigue is spiking and your half marathon is in 3 weeks. Dialing back tomorrow.6:48 PM
Keep the long run Saturday or cut it?6:49 PM
Keep it but cap at 10km easy. Forecast says 28°C and humid Saturday - start by 7am, hydrate the night before. I'll check your WHOOP recovery in the morning and dial the pace.6:49 PM

What athletes are saying

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.

Runner, sub-1:30 half marathon

It moved my leg day when it saw I had a tempo run the next morning. No other app connects lifting and running like that.

Hybrid athlete, runner + lifter

It caught my easy pace drifting 15 sec/km faster over two weeks and told me to back off. That used to take me weeks to notice on my own.

The onboarding really impressed me - it immediately spotted that my FTP setting didn't line up with the power I was actually putting out in sessions.

The ChatGPT integration just wasn't what I needed it to be. athletedata does a much better job.

I asked for an intervals.icu integration and it was live a few hours later. That kind of responsiveness is unheard of.

I want to go sub-3:30 at my marathon in October. Am I on track?
Your long run pace has dropped from 5:20 to 5:05/km over 6 weeks and your Garmin VO2max is trending up. But your WHOOP HRV dips after back-to-back hard weeks. I'd add a proper deload every 4th week and keep your easy runs under 5:30/km - you're drifting too fast on those.
02

Chat on Telegram

Text your coach like a friend. It already knows your workouts, sleep, and recovery. No screenshots or copy-pasting needed.

03

Get proactive coaching

Your coach tracks training load, sleep, HRV, and recovery - spots when volume is spiking, flags fatigue before you feel it, and adjusts your plan before race week. No need to ask.

athletedata.healthAfter your long run
18km at 5:08/km with perfect negative splits - your best long run this block. WHOOP strain was 14.2 and Garmin training status shows you're peaking. You're absorbing the volume well. Keeping Thursday's tempo session but capping it at 6km at threshold.

The missing connection layer

Endurance athletes use 4-6 apps that don't talk to each other. athletedata connects them all - so your coach sees your morning HRV alongside last night's sleep, yesterday's workout, and your race calendar.

Frequently asked questions

Everything you need to know about athletedata.health

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, and you can delete everything permanently at any time from your dashboard.

What can the coach actually do?

Anything a knowledgeable coach could do if they had instant access to all your training data across 50+ metrics from Strava, Garmin, WHOOP, Oura, Hevy, Intervals.icu, and more. Track training load across sessions. Build periodized plans for your race. Detect when volume is spiking too fast. Plan race tapers, flag overtraining via HRV and sleep, and adjust intensity based on recovery - all grounded in your real numbers.

Is the coach a real person?

No, it's an AI powered by Anthropic's Claude that has direct access to your training data via secure API integrations. It maintains a persistent athlete profile with your goals, injury history, and preferences, and remembers context across every conversation so the advice improves over time.

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.

What fitness apps does athletedata.health integrate with?

athletedata.health integrates with Strava (running, cycling, swimming), Hevy (strength training), WHOOP (recovery, strain, sleep), Oura (sleep, readiness, HRV), Withings (body measurements, weight, body composition), Garmin (activities, sleep, body battery, stress, body composition), Intervals.icu (training load, power curves, wellness, planned workouts), Google Sheets (food logs, blood work, lab results), and Google Calendar (race dates, planned sessions). More integrations including Apple Health are coming soon.

How does AI fitness coaching compare to a human personal trainer?

An AI coach has instant access to all your data across every platform - 50+ metrics from workouts, sleep, HRV, and recovery - and can analyze trends across months of training in seconds. It's available 24/7 via Telegram, remembers every conversation, and proactively reaches out when it detects overtraining risk or recovery dips. A human coach brings empathy and hands-on form correction, but can't match the data depth or availability. Many athletes use both.

Can AI analyze my Strava data and create a training plan?

Yes. athletedata.health connects directly to your Strava account via OAuth and can access your full activity history including pace, heart rate, power, cadence, elevation, and route data. It uses this data along with your goals, injury history, and recovery metrics from WHOOP or Oura to build periodized training plans tailored to your actual fitness level.

Does athletedata.health work with WHOOP recovery data?

Yes. athletedata.health integrates with WHOOP to pull recovery scores, strain data, HRV trends, resting heart rate, and sleep performance. Your AI coach uses this data to adjust training recommendations in real time - for example, suggesting an easy day when your recovery score is low or flagging when your HRV trend indicates accumulated fatigue.

How does the AI coach use sleep and HRV data?

Sleep and HRV data from WHOOP and Oura are central to the coaching. The AI monitors trends in sleep duration, sleep stages (deep, REM, light), HRV baseline and variability, and resting heart rate. It cross-references this recovery data with your training load to detect overtraining, recommend rest days, and optimize workout intensity. Studies show HRV-guided training reduces overtraining incidence by up to 30%.

What sports does athletedata.health support?

athletedata.health works for any endurance sport - running (5K to ultra), cycling (road, gravel, MTB), and multi-sport training. It also supports strength training via Hevy. It connects Strava, Garmin, WHOOP, Oura, Intervals.icu, Hevy, Withings, and more into a single coaching view. Whether you're training for a marathon, a gravel race, or an ultra, your coach sees your full training picture across every platform.

How does athletedata.health compare to Runna or NXT RUN?

Runna and NXT RUN are AI running coach apps that generate adaptive running plans. athletedata.health goes further by integrating recovery data from WHOOP and Oura, strength training from Hevy, and body composition from Withings into a single coaching experience delivered via Telegram. If you only run and want a simple plan, Runna or NXT RUN work. If you want coaching that accounts for your sleep, HRV, gym sessions, and recovery - and reaches out to you proactively - athletedata.health is the better choice.

Is athletedata.health the best AI fitness coach app?

athletedata.health is the only AI fitness coach that combines data from 5+ platforms (Strava, Hevy, WHOOP, Oura, Withings, Garmin, Intervals.icu), maintains a persistent athlete profile across conversations, and proactively coaches you via Telegram. Unlike Runna, NXT RUN, or Humango, it uses real recovery data from wearables - not just workout performance - to adapt your training daily.
