Ask your coach. Run the workout on Apple Watch.

Ask in the iPhone app. Surge builds the session from your runs. You confirm before it lands on the calendar, then it shows up in Apple’s Workout app — with pace alerts, not another watch face.

Surge · Scheduletoday

Easy 8 km tomorrow at 9. Then a half marathon in 1:49 from my Stockholm GPX — start conservative, finish faster.

Ready to confirm: Easy 8 km tomorrow at 09:00. A half needs 1:49:00 so the paces come from the engine. Nothing is saved until you confirm.

The coach is in the iPhone app. The plan comes from your runs, and nothing is saved until you confirm.

01 · Ask

Ask in the iPhone app

On the Coach tab, ask for a run, a plan, or a race preview. Surge uses the runs you have uploaded. You confirm the card before it is written to the calendar.

“Easy 8 km tomorrow.”
“Build my next 6 weeks.”

02 · Compile

Real splits, not invented paces

Race pacing is a fixed engine: official distance, target time, optional elevation from a GPX. The model does not invent kilometre paces. Easy runs, intervals, and plans land as structured steps with one alert per step.

03 · Watch

Apple’s Workout app, with your icon

Open Surge on iPhone. The session shows up on the Watch for about the next week. Start it like any other Apple workout — haptics included.

Also available

Claude, ChatGPT, and Cursor still connect.

Surge is still an MCP server. Those clients can create, move, and cancel workouts, import a GPX, or build a half marathon plan. New training features go into the iPhone app. The tools stay, and they will not gain new ones.

You sign in once. Claude or Cursor then acts as you — it never invents your account.
The same calendar the iPhone sees.
An external client writes as soon as the tool succeeds. The confirm step is in the app.
A GPX informs pace. Apple Watch will not navigate the route.

What to expect

The Watch shows about a week

Your full plan lives in Surge. Apple Watch lists roughly the next seven days, at most 15 workouts. Farther sessions appear when that week arrives.

Open the app to send workouts

There is no guarantee a silent push will land. Open Surge (or wait until the next time you do) to put workouts on the Watch.

What we are not building

No custom Watch workout screen, no live coaching mid-run, no Android, no turn-by-turn maps.
