What Devices Does Coachline Work With?
Which devices does Coachline support today?
Garmin watches that track running. Connect one and your runs arrive on their own — distance, time, pace, heart rate, elevation — along with the recovery and sleep data your watch already collects.
That's the honest current list. More integrations are being worked on, and we'd rather tell you what works today than publish a wishlist.
What does Coachline read from your watch?
- The run itself. Distance, time, pace, heart rate average and max, elevation gain.
- How you're recovering. Sleep and recovery figures, which is what lets a session get easier on a bad week without you asking.
- What you didn't do. A quiet week is information too, and it's part of what the next adjustment is built on.
None of it requires you to open anything. The run finishes, the data arrives, and your coach texts you about it.
Can you use Coachline without a wearable?
Yes, and this isn't a degraded mode bolted on as an afterthought. It's a supported way to use the product.
Instead of a sync, you check in. You tell Coachline what your typical week already looks like when you start, you text it what you ran afterwards, and you tell it how hard the effort felt. That last part matters more than people expect — a watch reports your heart rate, but only you can say the run felt like a slog.
| With a Garmin | By text | |
|---|---|---|
| Your runs | Arrive automatically | You text what you ran |
| Pace and heart rate | Exact | Your estimate, or skipped |
| Sleep and recovery | Read from the watch | You mention a rough night |
| How hard it felt | You tell it | You tell it |
| A real training plan | Yes | Yes |
What does a manual check-in look like?
No watch produced any of that. The distance, the time and the effort all came from one text.
Is the plan worse without a device?
It's less precise, not less real.
With a watch, Coachline can see a bad night before you mention it and can tell the difference between a steady hour and an interval session with the same average heart rate. Without one, it works from what you tell it — which is exactly what human coaches worked from for decades, and they produced plenty of good runners.
What doesn't change is the plan underneath: a structured block built toward your goal, adjusted as your weeks actually go. You can also start without a device and connect one later. Nothing has to be rebuilt when you do.
