Your Plan Now Pushes to Your Watch (and Why Strava Had to Go)

July 4, 2026

Strava turned off its API for apps like mine on the first of July.

If you connected Strava to HybridX to pull your runs in, that stopped working. I'd rather be straight with you about it than let it quietly break: the door Strava opened to small apps is, for now, closed. I was on a short extension, and it runs out at the end of the month.

Here's the honest part — I'm not that sad about it.

Strava was only ever half a bridge

Strava could import your runs. Distance, pace, heart rate, landing in your log the same day. Useful. But it only went one direction: activities came in. The plan HybridX wrote for you never went out to where you actually train — your watch. You'd still stand at the start of a session, look at "3 × 4 min threshold" on your phone, and either memorize it or thumb it into your watch by hand.

That's the gap that always bothered me. The plan lived in one place, the workout happened in another, and you were the sync cable in between.

So instead of chasing another read-only import, I built the direction that was missing.

Your planned run now writes itself into your watch

Connect Garmin, and every planned endurance session pushes straight to your Garmin Connect Calendar and onto your watch — structured, in order, with pace and heart-rate targets on each step. Warm-up, the hard middle, cool-down. You wake up and the workout is already there. Press start and run it.

A threshold session lands like this:

15 min warm-up, Z1–2
3 × (4 min threshold Z4 / 2 min float)
10 min cool-down

No retyping. No screenshot on your forearm. And when you're done, the completed activity flows back into your plan the same day, so tomorrow's session is written against what you actually did — not what you were supposed to do.

Not just Garmin

Garmin's great if you have one. Plenty of you don't — you're on COROS, Wahoo, Polar, Suunto. I didn't want push to be a Garmin-only feature.

So HybridX now also connects through intervals.icu. If your watch syncs to intervals.icu — most do — HybridX writes the planned workout there and intervals.icu hands it to your device. Same round trip: planned runs out, finished activities back. I test this one on myself. I'm on a COROS, and my week now lands on my wrist without me touching it.

Two integrations, both going both ways. That's the whole connections screen now: Garmin, or intervals.icu. Strava's gone from it.

What doesn't push, on purpose

Your runs and rides push. Your lifting sessions don't.

I tried sending strength days too. A structured lifting session shows up on a watch as a wall of text you can't follow mid-set, and it clutters the one screen you want clean when you're running. So HybridX only sends the endurance work to your device — the stuff a watch is actually good at guiding. Your strength plan stays where it belongs, in the app, next to the run it's balanced against.

If you were on Strava

You don't have to do much: reconnect. Open Connections, link Garmin or intervals.icu, and you're back — with more than you had before, because now the plan goes to your watch instead of only reading from it.

Strava leaving forced the move. The app is better for it. The plan finally meets you where you actually train.
