Jeffrey Inscho of Static Made making a case for running in silence:
While the music, tech musings and automated metrics kept my mind from focussing on the discomfort my body was feeling, I also discovered that this constant connectivity (even while in the middle of the woods on a trail run) was keeping my mind from appreciating my surroundings in those moments, following an exploratory train-of-thought around professional ideas and concepts, or simply experiencing the silence and patterns in my breath.
As much as I love running with music, Jeffrey has a great point here. The times I’ve ran without music, my mind has been free to wander and contemplate. I’ve often had great ideas while running without music. These days I tend to do my weekly long run without music.
