Went out to pound out a garage ride this evening and the speed/distance sensor wasn't being detected by the Garmin. I pedaled away, anyway.
I realized an analogy between undocumented exercise and an anonymous small act of kindness. Exercise is a kindness we offer to our bodies. And it's nice to have a marker or two about our endeavors to gauge progress, but it's not necessary. Just the same as praise for a kindness is not a requirement. The blessing in knowing you did it is all that is needed.
