Built an AI coach for triathletes that reaches out to you - not the other way around

Heyy!! thanks for signing up!

  1. I just reached out to the TP Team asking for an integration - I´ll keep you posted on the progress.
    As a workaround for now, you can just upload screenshots via telegram. athletedata can see those.

  2. You can send PDFs via telegram as well - athletedata will read and analyze it to give you personalized responses.

PS: voice messages work as well :wink:

If you have any other questions, just hit me up!

Quick update - a few more metrics are live and being computed in our own data pipeline.

With the last bigger update, I essentially built our own data aggregator pipeline where we compute a ton own metrics so the coach (or MCP) can reference those easier and much faster.

How it works:

  • we compute everything once when you connect your integration
  • whenever new data gets synced, we recompute → so its always up to date

P.S. Please excuse the sleep deficit - athletedata kept me burning the midnight oil lmao

Hi, I managed to enroll, but I am not seeing any of the stuff you are sharing. I linked my Garmin account and google calendar, but I am only seeing this:

will enable the feature flag for mcp only users (will be at home in about 20minutes) - will keep you posted

enabled :slight_smile:

Thanks Julian! Apparently my activities from Garmin are not imported, because all charts except the health related ones are empty with a message that says “No activity data yet”

Its probably because you did not enable “Historical Data” when connecting Garmin, its disabled by default ;/

Please disconnect Garmin and reconnect it again with the “Historical Data” thingy toggled.

I also added a hint in the garmin integration tile for future reference.

Let me know if that worked - Cheers!

I may have missed it in the thread but wondering what functional difference is there between the normal subscription and where you use an MCP subscription? Is it related to historical context?

athletedata MCP plan ($9/mo or $69/yr):

  • you use your own paid Claude or ChatGPT subscription to chat with your data
  • you get the full data aggregation pipeline (Strava, Whoop, Oura, Garmin, Hevy, Withings…) + our own computed metrics
  • no proactive coaching, no Telegram bot
    → basically “chat with your training data inside Claude/ChatGPT”

athletedata coaching plan ($39/mo, or $299/yr):

  • everything in the MCP plan
  • proactive coaching via Telegram (reacts to your workouts, sleep, recovery) and does everything proactively - you dont need to ask
  • securely hosted AI that does not get trained on your data
  • persistent athlete profile + memory, so you don’t re-explain yourself every chat

tldr: MCP = BYO-LLM, data only. Coaching = full hands-on coach in Telegram.

Let me know if that explains it :slight_smile:

thanks that does help.

Looks like a tidy solution for busy beginners. I wonder if I’m alone in seeing planning as the “main thing” about triathlon as a competitive sport - figuring out how to peak for a complex physical effort, deciding how far to take each session, building deep self-awareness, believing in your own strategy etc. By outsourcing all the decisions, all that’s left is exercise.

I think I had done that, but disconnected and reconnected again, but still no data.

hmm can you reach out to me via email so we can look into this closer. julian@athletedata.health
Just to be sure, you do see activities in your garmin connect app, right?

Thats a real tension, and I dont want to hand-wave it.
It really depends on what you want from a coach (or athletedata in this case) tbh.
athletedata can also just synthesize your data and surface options, but you can still decide when to go harder, when to back off, when to trust your legs over the numbers. (if thats what you want)

But frankly, if the intellectual puzzle of building your own system is the point for you… totally valid, and this probably isnt the right tool. the MCP tool to “chat with your data” could be a good layer on top for you though.

Another big update batch for athletedata - here’s what shipped recently:

Coach & analysis improvements

  • Added advanced reasoning to the AI coach for more nuanced responses

  • Improved interval analysis

  • Better long-term training plan reasoning (think: triathlon in 6 months, building back properly)

  • Proactive plan change suggestions now react more smartly to your data

  • Zone distribution now shows % alongside hours

Billing & flexibility
You can now pause and reactivate your plan at any time (not just cancel) — a few people reached out after getting injured and not wanting to lose their setup entirely. You can also switch between monthly and yearly mid-cycle, with unused days credited/refunded automatically.

Data & integrations

  • Got access to more Oura data again

  • Fixed a Garmin HRV data bug

  • Added explanations to all analytics metrics so you know exactly how things are calculated

  • New custom metrics added to the aggregation pipeline

  • Proper profile settings are finally in

Coming up

  • WhatsApp integration → I know a lot of you are waiting for this, it’s my main focus right now

  • Reached out to TrainingPeaks and MyFitnessPal → confident we can get full integrations soon once we can show them demand (they acknowledged it)

Super grateful for all the support and feedback guys - we are really building something really really cool here!
As always, feel free to reply here or DM me with anything.

Be honest, which AI writes your responses in the thread? :smiley:
It has all the signs of AI generated.

Hey, I noted down that you had concers regarding the Telegram connection, so I just wanted to let you know that the Whatsapp coach option is live now :smiley:

BIG update guys (2026/04/12):
WhatsApp support is now live.
A few of you mentioned Telegram was a barrier, so I prioritized this.

Give it a try and let me know how it goes - looking forward to your feedback.
