I'd been struggling to make more than one 5K run a week happen.
I know how important running is for both my cardiovascular health and my mental health, so I wanted to find a way to increase the amount I was running without making it feel overwhelming.
With a big weekend away coming up in 25 days, I set myself a simple challenge: run for 10 minutes every day.
Here's what happened.
π Burned an extra 160 calories per day
According to my Garmin, my average active calories burned per day increased from 465 to 626.
Each 10-minute run burned around 120 calories, which added up to roughly 1,120 extra calories over the course of a week.
β€οΈ Doubled my weekly intensity minutes
My average daily intensity minutes increased from 12 to 25.
In other words, I more than doubled the amount of time each week that I was getting my heart rate up and challenging my cardiovascular system.
π Increased my VOβ max
On day 23, my VOβ max increased from 39 to 40.
VOβ max is a measure of how efficiently your body can use and circulate oxygen during exercise, and it's not an easy metric to improve.
I was genuinely delighted to see it increase during this experiment. It was a great reminder that consistency often matters more than the length of any individual run.
π I started to love it
Spending 10 minutes moving before the day started became something I genuinely looked forward to. I picture running through the crisp morning air in the park and it makes me smile.
π I got my dog running too
The short runs were also the perfect way to get Mikey started as my running buddy.
He picked it up surprisingly quickly, although he definitely found it tiring at first!
The reason I run is simple: cardiovascular health and mental health.
This experiment showed me that both can be improved with just 10 minutes a day.
I'm going to take a short break, enjoy the next week or so, and let my body recover. After that, I want to keep the streak going and maybe even increase it to 12 minutes a day πββοΈπ€©
