Custom interval workouts on Apple Watch — with pace and heart-rate targets that actually guide you

Structured training is where the Apple Watch's simplicity stops being a virtue: the Workout app can time intervals, but turning a coach's session — 6 × 1 km at threshold, 90 s jog, warm-up and cool-down easy — into something the wrist enforces takes more. Here is how custom interval workouts on Apple Watch work in Vanoor, what the Watch does at every step, and an honest comparison with Apple's built-in custom workouts.

Vanoor's workout editor on iPhone: steps with distance or time, pace band, heart-rate zone, repeat blocks — **Build it on the iPhone**Steps, targets, repeats, fuel cues.

Building a workout

My Workouts → +. A workout is a list of steps; each step has an extent and a target:

Extent: a distance (400 m, 1 km, 5 km…) or a duration (90 s, 20 min…).
Target: open (no target), conversational (easy, by feel), a pace with a band (4:15/km ±15 s), a heart-rate zone (Z2–Z5), or a heart-rate range (140–150 bpm).
Repeat blocks: group work + recovery and set the count — 6 × — instead of typing twelve steps.
Fuel cues: a nutrition reminder at any time or distance.

Attach a GPX route if the session has a place (a track, a loop, a race course) and the map runs alongside the intervals. Save, and the workout syncs to the Watch.

Three sessions to copy

Session	Steps	Targets
Threshold	Warm-up 2 km · 5 × (1 km + 90 s) · Cool-down 1.5 km	Easy · pace band at ~10K–half pace ±15 s · easy
Long run with quality	Easy 12 km · 6 km · Easy 2 km	Zone 2 · marathon pace band · conversational
Hills	Warm-up 15 min · 8 × (60 s + 2 min) · Cool-down 10 min	Easy · HR range 165–175 · open

What the Watch does during the session

Announces every step with a full-screen card and a buzz before it starts, so you know the target before you are in it.
Shows the target band and your live pace (or heart rate) inside it — green in, red out — plus the distance or time left in the step.
Pace and heart-rate off-target alerts, if you turn them on, tap you when you drift for more than a moment; you do not get nagged every second.
Counts down the last seconds of a recovery with growing taps, so you are ready, not surprised.
Saves the whole session — every interval as a segment — to Apple Health, and to Strava if connected.

Vanoor vs. Apple's built-in custom workouts

Apple's Workout app has had custom workouts since watchOS 9, and for simple sessions they are good. The differences that matter for structured running:

	Apple Workout app (custom workouts)	Vanoor
Steps by distance or time	Yes	Yes
Pace target	Alert when outside a range	Band shown live on screen + optional alert
Heart-rate target	Zone or range alert	Zone or range, shown live + optional alert
Repeat blocks	Yes	Yes
Fuel / nutrition cues	No	Yes, at any time or distance
Route attached to the session	No (Race Route re-runs your own recorded routes only)	Any GPX or drawn route, with offline map
Race pacing plan from a goal time	Pacer (even pace only)	Negative / even / positive split planner
Where you build it	On the Watch	On the iPhone, synced to the Watch
Price	Free	$9.99 once, 7-day trial

Apple feature availability checked against Apple's watchOS documentation on 18 September 2026; details vary by watchOS version.

If Apple's custom workouts already do what your training needs, use them. Vanoor earns its place when the session has a route, a fuel plan, a pacing curve, or you simply want to see the band instead of waiting for an alert.
