The fastest way to build workouts in intervals.icu
intervals.icu is a great home for a training calendar — but its native workout builder is built for precision, not speed. Every interval is its own row: duration, target, cadence, repeat count, each one a separate click. For a simple endurance ride that's fine. For a six-part interval session, it adds up.
Why the native builder is slow for real sessions
A coach doesn't think in rows and dropdowns. You think: "warm up, then three sets of twelve minutes at sweet spot with four minutes easy between, then a couple of short efforts to finish." Translating that sentence into intervals.icu's builder means manually adding each block, setting its power target as a percentage of FTP, setting cadence if it matters, and getting the repeat structure right — then double-checking it before you send it, because a misplaced rest interval is easy to miss until an athlete is halfway through the wrong workout.
Describe it like you'd coach it
Wattscribe skips the form entirely. You record yourself describing the session the way you'd say it out loud to a rider:
"Fifteen minute warm up, then three times twelve minutes at sweet spot, ninety percent FTP, four minutes easy recovery between each. Finish with two times three minute VO2 efforts at a hundred fifteen percent, three minutes easy after each. Ten minute cool down."
That's it — no forms, no dropdowns, no manual repeat-count math.
What that turns into
Wattscribe parses the warm-up, the two distinct interval blocks (with their own durations, targets, and rest), and the cool-down into a structured workout you can see and adjust before it goes anywhere — fix a target, nudge a duration, change a rep count, all without re-recording.
One push, straight to their calendar
Once it looks right, send it directly to an athlete's connected intervals.icu account and it lands on their calendar — no exporting, no re-entering it a second time in a different tool. If they're not on intervals.icu, export the same workout as a .ZWO or .FIT file instead.
