Workout Complete on Running Day

For the last 2 days, I was on vacation and went running for 30 minutes for my workout. On my calendar, there are no check marks to mark I worked out, even though I did a good workout. Does anyone ever put a workout on the their calendar and just mark complete on a running day so it has a check mark? I am guessing some would frown upon this. On the calendar day, I wrote a note that I ran on Monday and Tuesday but for some reason I hate that there is no check mark. On my fridge calendar I put a W in blue to mark my workouts. Just curious.
