I investigated: Can AI replace your ultra running coach?
Rather than just asking AI what it could do, I decided to actually use it on my own training.
I gave it information about my training, asked it questions, got it to analyse things, suggest sessions and challenge some of my decisions.
Basically, I wanted to find out:
If I didn't have a coach, could AI do the job?
And honestly… AI is good for so much and it is worth embracing........
But after using it myself, I found some pretty big limitations:
• It doesn't really know you
It knows what you tell it, but it doesn't truly know the person behind the data.
• It can make mistakes — and confidently present them as fact
It can misunderstand something, give you the wrong answer or pull together information that isn't quite right.
• It doesn't see the whole picture
Sleep, stress, work, family, motivation and niggles can completely change what the right training decision is.
• It can lose context
Even after giving it loads of information, things can be missed, forgotten or misunderstood.
• It takes your time
You have to keep feeding it new information — what you've done, how you're feeling, how you've slept, what's changed — and then check whether its recommendations actually make sense.
• Coaching is about judgement
Knowing what session you should do is one thing. Knowing when to push, when to adapt and when to say don't run today is another.
But here's the thing…
I'm not anti-AI.
Far from it.
After using it myself, I think it's an incredible for certain tasks......
But would I replace a good coach with it?
No.
Because a training plan is only part of coaching.
Understanding the person following it is the other part.
I've done the investigation.
Now you decide.
Could AI replace your ultra running coach?
