If you want a free, no-frills plan that lives on your watch and adapts based on your workout performance, Garmin Coach is excellent. It's built into Garmin Connect, requires no subscription, and works seamlessly with your watch. For many runners, it's all they need.
If you want a coach you can actually talk to - not just a plan that adjusts paces, but one that explains why, considers your life (travel, sleep, stress), and adapts everything from recovery to race strategy. GraviRun is for runners who want to understand their training, not just follow it. Connect your Garmin account and your activities sync in automatically, so the conversation starts from your data-backed reports and pause/recovery insights - not a blank page.
