If you want a personal relationship with someone who knows your life, has raced your races, can read your body language, and adapts with genuine human intuition - a human coach is irreplaceable. A good coach sees things AI can't: how you're moving, how stressed you look, what you're not saying. If you can afford $100–300/month and value that human connection, hire one.
If you want coaching that's available at 5 AM before your run, adapts instantly when you tell it "I slept terribly" or "I'm traveling all week," and costs a fraction of a human coach - GraviRun is built for that. It won't replace a human coach's intuition, but it will give you 90% of the coaching value at 5% of the cost, available whenever you need it. Many runners use GraviRun alongside a human coach - the AI handles day-to-day questions, the human handles the big picture.
