Feel the core (Jan 23, 2024)

Very cold tonight. It's gonna be snowing tomorrow.

I enjoyed running my usual course tonight, thinking of my stride. My average stride length is usuallly about 1.20m, and at the race last year about 1.30m. I think my stride in my high school age was 0.2m longer, though I couldn't run more than 10km. 

Step by step. I have added some exercise to training my core.
