Let’s start with something you probably didn’t expect to read on a coaching website: I used AI to help write this blog post.
I know. Stay with me.
Because here’s the thing, AI is genuinely useful. It can research, organize, draft, and produce content faster than any human. I’m not here to tell you technology is bad. I coach athletes for a living. I know that tools matter.
But there’s a difference between a tool and a coach. And right now, a lot of runners and triathletes are confusing the two, and paying for it on race day.
The App Told Me to Run 8 Miles. So I Did.
Your AI training plan doesn’t know that your left knee has been talking to you for three weeks. It doesn’t know you had a terrible night’s sleep because your kid was sick. It doesn’t know the humidity hit 90% this morning and your “easy 8 miles” just became a survival march.
It just said 8 miles. So you ran 8 miles. And now your knee is angry.
I’ve been running for 32 years. I’ve seen this pattern hundreds of times. The athlete who follows the plan perfectly, and breaks down because the plan didn’t know them.
An algorithm can build a plan. It cannot read your face when you show up to group training at 5:30am looking like you haven’t slept in three days. I can. And I will absolutely modify your morning around that, because I know the difference between an athlete who needs to be pushed and an athlete who needs to be managed.
That’s not something a language model learns from your heart rate data.
What 32 Years in the Sport Gives You
I ran my first race in 1993. I’ve trained through heat, snow, woke up at 5am in 2 degree temps, hurricanes, injuries, bad seasons, great seasons, and one memorable 50K.
In those 32 years, I’ve learned things that don’t exist in any database. I know what a runner looks like when they’re about to hit a wall three miles before they think they will. I know when an athlete says “I feel fine” and means it, versus when they say “I feel fine” and are lying to themselves. I know which athletes train great alone but fall apart in race environments — and how to fix that.
You cannot compress 32 years of real experience into a training plan prompt. You can’t ask ChatGPT “what does a runner look like six weeks before they quit?” and get an answer that’s worth anything.
Experience isn’t data. It’s pattern recognition built from being there, in person, in conditions, in the real world — over and over and over again.
The Group Is the Secret Weapon
Here’s what no app is giving you: the energy of 30-60 people showing up at 5:30am.
When you train alone with a plan on your phone, motivation is entirely on you. Some days that works. Most days, if we’re being honest, it doesn’t. You negotiate with yourself. You shorten the run. You skip the tempo intervals.
In a group, something different happens. The person next to you is going. So you go. The pace picks up. You find something you didn’t know you had. You finish a workout you would have quit at mile 2 if you were alone on a treadmill.
That dynamic is not replicated by any app, any algorithm, or any AI. It is a human thing. It requires human beings in the same space, at the same time, suffering and succeeding together.
Motivation delivered through a push notification is not motivation. Motivation is your training partner refusing to let you slow down with 400 meters left.
I’ve watched athletes nail every workout in their training plan and then fall completely apart in a real race environment. You want to know why?
Because they trained in a controlled environment and expected race day to be controlled.
It isn’t.
Race day is humidity and headwinds and a porta-potty line that cost you four minutes and a nutrition strategy that stopped working at mile 9. Race day is the athlete who goes out too fast in the first mile and blows up by mile 6, because no one ever taught them what controlled effort actually feels like in a crowded race start.
When I coach athletes onsite, I teach them to train in the real world, in real conditions, with real obstacles, with real people around them. We run the hills that hurt. We do brick workouts in heat when it would be easier to reschedule. We practice start-line strategy because the start line is where bad decisions are made most often.
A training plan tells you what to do. A coach teaches you how.
The Collaboration Nobody Talks About
Here’s the part that gets left out of every “AI vs. human” conversation:
The best coaching relationships are collaborations.
When I build a plan for an athlete, I’m not handing down commandments. I’m starting a conversation. How did that feel? What’s your body telling you? What happened at work this week? Are we being realistic about this timeline?
That back-and-forth, the athlete’s honest self-reporting, my experience interpreting it, and the ongoing adjustment of the plan, that is where results come from. Not from the plan itself. From the process of building it together, in real time, with a human being who gives a damn whether you make it to the finish line.
So Where Does AI Fit?
I’ll be straight with you: I use AI tools to make my coaching better. I use them to organize, to research, to communicate faster with athletes, to help produce content like this. Technology makes me more efficient.
But efficiency is not coaching. Efficiency is infrastructure.
The coaching is me, on the track at 5:30am, watching how you’re moving, adjusting your effort, pushing you past what you thought was your limit, and celebrating with you when you cross a finish line you weren’t sure you could reach.
Thirty-two years of that. No app included.
The Bottom Line
Use the apps. Track your data. Listen to the podcasts. Read the blogs. I’m not against any of it.
But if you’re serious about your running or triathlon, if you have a real goal and a real timeline and you actually want to get there, hire a coach. A real one. One who’s been where you are, has seen what you’re going through, and will be standing there at the track when the plan says easy day but your body says otherwise.
Success in endurance sports doesn’t come from the perfect algorithm. It comes from collaboration between an athlete who shows up and a coach who knows what to do with them when they do.
The work is still the work.
Do the work.
