Interval Editor

What it is

An editor for your own interval workouts. An interval workout mixes hard efforts with easy ones, like a fast lap and then a slow lap. You build the plan one step at a time. That means a warm-up, the work, the recovery, the cooldown, and any repeats. Save it, and it shows up in your Interval Library. From there it can run a live cardio session.

How it works

Open the Interval Library. Tap + to start a new plan. Or long-press one you already have and pick Duplicate to start from a copy.

In the editor you can set:

• A name and description.
• A list of steps in order: warm-up, work, recovery, cooldown, or rest.
• A target per step in distance (meters) or time (seconds).
• A pace target per step, if you want one.
• A repeat block. Wrap a few steps in a ”× 8 rounds” group.

Every row has move up, move down, and delete. The plan itself has save and delete.

You can’t change a built-in plan on its own. But you can copy it. The copy gets a “Copy” label. The editor opens on the copy, and that one is fully yours.

Why it’s free

Custom interval workouts are core to tracking. They aren’t an extra you pay for. Track 400m repeats, fartlek sets, indoor bike efforts, or swim ladders. A fartlek mixes fast and slow running in no set order. None of this should need a subscription to log.

Two PRO features sit next to this. One looks at your pace zones (Zone Training). One offers run coaching that adapts to you (AI Coach). Both read your interval sessions once you log them. The editing itself is free.

Use cases

• 400m × 8 with 90s rest — a classic speed session
• Fartlek 30s on / 30s off × 20 — loose speed play with some shape
• 5-minute climbs × 4 — indoor cycling at a hard, steady effort
• Pyramid 100/200/400/200/100 — a swim ladder with stroke breaks
• Zone-2 90 minutes — one long, easy effort for recovery days
