I haven't been riding in forever. My riding preferences have changed in recent years. I'm super casual and ride my bike really slow. I like to look at the scenery more than I like to get someplace fast. So, given my ultra casual mindset, I wrote it off as a calorie burning endeavor.
Today, the Mrs took care of the kid and I got to ride to work, around at lunch and then home. This is my ride home. About 40 minutes. I forget my average speed, but it was slow, yet I still got an average of approximately 120 bpm when I used my heart rate datalogger. I went from work to Giant Eagle and then home. Mostly all up a gradual hill, but not a bad workout. I'm pretty psyched to have another exercise to alleviate the boredom of cardio.
