Help finding anaerobic sprint workout

Hi all,

My planned ride wouldn’t allow an outside selection so I did the sprint suggestion from Garmin.

I’d like to update my calendar with a similar workout and pair it.

1hr workout.
15min at endurance
2x16 10s on 20s off, 5min break at halfway
15 min endurance

Tried the workout filters but not seeing anything. My first thought is Spanish Needle?

Couldnt find anything just right so went with Tyndall -4, which is longer durations at around 380W.
