A coach that plans your week. Not an app that counts it.
Paceform reads your runs, writes next week's training, and sends it to your watch. If you miss a run, next week adjusts.

Sub-threshold cruise intervals
The main quality session this week — steady time just under threshold builds the engine without wrecking tomorrow.
Sends all 4 sessions to your watch
Welcome. I've looked at your last three weeks and here's what I see: your easy running is genuinely easy — heart rate sitting comfortably in the aerobic zone at roughly 7:30–7:40 per kilometre, which is a good foundation. You threw in a VO2 max session two weeks ago that looked sharp (9 minutes of actual VO2 max work, max heart rate 180), and last week's threshold attempt only produced 8 minutes of quality at sub-threshold before it faded — probably a pacing or fatigue issue, not a fitness ceiling. Volume has been modest, 12–22 km per week across 2–3 sessions. Your goal of 1:50 for the half marathon requires a lactate threshold pace of roughly 5:13 per kilometre. You're not there yet, but September 2026 gives us time. This first week I'm keeping things conservative: three easy runs plus one sub-threshold session to establish the quality habit without spiking load. A few assumptions I'm making — correct me if wrong: you have no current injury or soreness, you're comfortable running 4 days per week from the start, and last week's low volume (12 km, 2 sessions) was circumstantial rather than a sign of fatigue or illness.

This week’s sessions
Keep your heart rate in the easy aerobic zone throughout. This is base-building mileage — it should feel genuinely comfortable, not moderate-effort.
How it works
Connect your watch
Link intervals.icu once. Paceform reads your runs and works out your zones from your heart-rate data.
Get your week
The coach looks at what you ran and writes next week: distances, paces, heart-rate bands, and why.
Run it off your wrist
One tap sends the whole week to your watch. It guides you through warm-up, reps and recoveries.
A week from the coach
A real plan, generated the same way yours will be.
Built around sub-threshold training — the approach Norwegian distance runners made famous.

I built Paceform for myself. Every other app I tried was either too much — endless dashboards and settings — or too expensive. I just wanted one place to check in once or twice a week: get honest feedback, get next week's workouts, chat through anything, and have it land on my watch. In a busy life, five minutes for a whole week of expert-level coaching is golden. That's the whole app.
Before you ask
Which watches work, and how do I connect?
Garmin, Coros, Wahoo, Polar, Suunto and more — you link yours once through intervals.icu, and Paceform reads every run from there for coaching. Automatic workout delivery to the watch works with Garmin, Coros, Wahoo and Suunto; Polar and Apple Watch can't receive planned workouts (a limit of those platforms), so you follow those sessions in the app. You can start planning first and connect later.
What if I miss a run?
Nothing breaks. Paceform reads what you actually did and builds next week around it, instead of piling the missed work on top.
Is my health data safe?
You can withdraw your health-data consent at any time (it pauses coaching), and export or delete your data whenever you want.
Can I cancel any time?
Yes, whenever you like — no notice period, no fees. And your founding rate sticks as long as you stay subscribed.
Who's it for?
Runners who want structure without a spreadsheet. Racing anything from 5K to marathon, or just getting fitter — you pick a goal during onboarding and the plan follows.
