The new year is a great time for nerds like me. If you’re a sucker for the joy of a new training journal, the fresh promise of a program you’ll check off one day at a time, or even (admit it) the kid who really loved filling in bubbles with a number two pencil, you’ll enjoy this bubble-style calendar that a generous Redditor posts each year.
Here is the 2025 version, available in two sizes, and with the week beginning with either Sunday or Monday, according to your preference. The user who posts it every year goes by u/Propelissa, so check their profile next January when you’ve filled up this one.
The two sizes are 8.5″x 11″, best for printing on a standard letter-sized American printer, and 8″ x 10″, best for submitting as a “photo” to any photo printing service.
How to use the bubble calendar
Honestly, it’s just a sheet of paper with circles on it, so you can use it any way you like. But it was inspired by this poster, apparently issued by Saucony and Fleet Feet in 2019, which invited you to fill in one of the bubbles every time you went for a run.
If you print the 8″ x 10″ version through a photo service, you’ll probably want to use a Sharpie to fill in the bubbles. But if you have access to a regular paper printer, you’ll get a grade-school thrill out of being able to fill in the bubbles with a nice Ticonderoga pencil.
Last year, I decided to use the bubble calendar to track my cardio. (It’s easy for me to keep up with strength training, less so with cardio.) If I did a bike ride, a run, or any other kind of purposeful cardio workout, I filled in that day’s bubble. If I went for a walk, I drew an X in the bubble to give myself partial credit. Toward the beginning of the year, most of my cardio workouts were power zone bike workouts; in the summer and fall, they were usually runs.
How you use the calendar is up to you. You could log any type of workout. You could use different colors for different types or lengths of workout. Or you could use the calendar to track how often you floss your teeth, or eat your vegetables, or make it to bed on time. Go ahead, it’s all yours.
