Have you tried to use the “Add Step” function in the workout builder and read this guide: Workout builder - Guide - Intervals.icu Forum
This syntax is useless: no target, “press lap” needs to be placed directly after the “-”. And bonus: the repeats can be added easier…
For example, the syntax based in HR zones (be sure they are configured in the settings…):
- Press lap 40m Z2 Pace intensity=warmup
10x
- 0.5mi Z2 Pace intensity=interval
- Press lap 0.5mi Z0 Pace intensity=recovery
- Press lap 20m Z2 Pace intensity=cooldown**
On a Garmin device, “press lap” always works, it wil skip end the interval and skips to the next one.
