by Grant Paling. It’s a new world. AI - particularly of the generative variety - is everywhere. We don’t google any more, we ask ChatGPT.
The companies that are doing well right now are the ones turning this from a gimmick or a parlour trick into a set of actionable, value-added use cases.
The world of AI multisport coaching was waiting for this to get to a certain point and I believe we have now reached that point. I’m speaking here as a user, not as an employee of AI Endurance, I am not. When Markus and I started up our partnership, my promise to him was to bring to you all a view from the athlete’s side. What is it really like to use an AI coach?

Regularly interacting with your AI Endurance “Coach” has never been easier
If you’ve followed my experiences the last couple of years, first of all thank you. I just write about my experiences as I go and I thank you for taking the time to read my rambling musings. I should note that AI writes 0% of my blogs. What triggered me to say this is that I cannot imagine AI using the phrase “rambling musings”. Or wasting a whole other sentence to write that thought about the thought out. Now where was I…
The experience. And the experience is changing. It’s getting more and more interactive. Key to this is using the Chat feature of AI Endurance and I find myself using it more and more.
I attribute this to a few things:

Recovery check-ins are now much more tailored and interactive with chat
Chat has been part of the experience all along - first by making AI Endurance available not just as an app but something you could integrate with your preferred GenAI interface (ChatGPT, Gemini etc.) from day one. Then it was integrated within the app so you didn’t need to leave the app (because many of us aren’t quite there yet where we are using one AI assistant to coordinate our lives - but if you are, it’s ready for that!). And now, the chat becomes not only a feature in the app but central to the AI Coaching experience, which is where it was going all along.
Here’s a few recent examples from my own playing with it.
Daily Check-In. The old check in was ok as a summary but never really differed much. Now - every day is more like a quick conversation with your coach. How are you doing? How are you feeling? Here is what is coming up tomorrow, do you feel ready? Already done - here’s what you should think about to maximise your recovery for the rest of the day.

The AI coach doesn’t just give you a blanket summary, it now asks follow up questions
I have other apps (I won’t name them) and I have also tried another app or two just on a free trial and I can tell you that the AI Endurance experience is a proper AI coaching experience. It’s AI that the app is built around, not just a bolted-on AI function that gives you a generic summary and rehashes what you already told you about your work out in slightly different words!
Race planning. I’ve long wanted this from AI Endurance and tried it before, and it worked ok. But now it isn’t a single summary with some rough targets, it’s a conversation. It’s a sounding board and that is what so many people need when they are in the lead up to a race (especially an “A” race). Let’s see where this goes next, I’ve made some requests about what I want to see. If you’re an AI Endurance user, why not use the AI Endurance forum and give your thoughts on this topic?
General questions. When I say general, I don’t mean asking it the meaning of life. I mean general questions about my data. Check out this one…

The age of AI is here. You can be afraid of it, you can try and ignore it – or you can embrace it. I for one, am getting a lot out of it. And I hope you will too. Let’s put those robots to work!

DFA alpha 1 is a heart rate variability (HRV) metric that allows tracking of the aerobic and anaerobic threshold. We explain the breakthrough potential of this new metric and how you can track your DFA alpha 1 thresholds with the AI Endurance app, Garmin and Zwift.

When it comes to triathlon training, nutrition plays a vital role in fueling your performance and optimizing your results. To help you reach peak performance, we have developed an advanced AI meal plan that takes into account your unique requirements, respects the calorie cost of your workouts, and accommodates your dietary preferences. With the power of evidence-based nutrition models, we ensure that your triathlon meal plan is tailored to support your goals.

by Stefano Andriolo, Markus Rummel and Iñigo Tolosa. We present a new real time feature of evaluating readiness to train based on in-activity heart rate variability (HRV) measurements during the warm up of your activity. You can use this feature in the newest version of the alphaHRV Garmin Connect IQ app at no additional cost.

by Stefano Andriolo. Building on previous work, we refine a method to accurately determine the relationship between DFA alpha 1 and power. This method can be used to track fitness and thresholds of an athlete. We find in some cases ramp detection tends to overestimate thresholds, a finding mirrored in recent physiological papers. On the other hand, thresholds based on clustering of DFA alpha 1 values tend to agree well with this new method. We propose a hybrid lab and everyday workout experiment to further study the relationship.
