Most coaching apps that call themselves "AI" are doing one thing: taking your goal race, looking up a generic plan, and handing it to you with a chatbot wrapper. That's not coaching. That's a search engine with better branding.
Real coaching is about context. Your coach knows you had three hours sleep because the baby was up. They know work has been brutal this week. They know you pushed hard on Tuesday and probably shouldn't hammer Thursday's tempo. They adjust.
Training science is well-understood. ATL (acute training load), CTL (chronic training load), TSB (training stress balance) — these metrics tell a sophisticated story about fitness and fatigue. Most apps calculate them in the background and then... ignore them when building your next week.
Miles doesn't. Every conversation feeds directly into how he thinks about your training. Tell him you slept badly — he adjusts. Tell him work is insane — he adjusts. Tell him you're feeling great and want to push — he checks your TSB first, then adjusts.
The biggest friction in any training app is the log. Did you run? How far? How fast? What was your effort? How did you feel?
Nobody wants to fill out a form after a run. They want to collapse on the couch.
Miles works differently. You tell him in plain English — "did 8km, felt okay but legs were heavy" — and he handles the rest. He asks one follow-up if something seems off. He updates your context. He moves on.
That's the difference between a tool you use for three weeks and a coach you stick with for three months.
There's a reason elite runners have human coaches: accountability, relationship, and the feeling that someone actually cares whether you finish that race.
Miles is built to provide that feeling. He remembers what you told him last week. He notices patterns you don't. And when race day comes, he's been there for every run in between.
That's not a feature. That's coaching.
