Keep the visual depiction in the calendar of the intervals when you switch a workout from inside to outside.
I do most of my workouts outside but have inside workouts set as a default so I can see what I’m up against for a given day/week. If I set it to outside as a default, there’s only the name of the workout in the calendar view, and then the wattage breakdown when you click on it. I think it’s way easier to mentally/physically prepare for what’s ahead if you can see the interval structure visually. Meaning I can plan the route/repeats I’ll do, eat enough calories throughout the day, choose what bike to use…etc.
Maybe keep the picture and invert the colors? or make the blocks green instead of blue if it’s outside?
