No you shouldn’t be concerned. What you’re doing is a form of HIIT training (ie: High Intensity Interval Training), which is great for cardiovascular health and boosting your metabolism.
While you’re choosing to perform HIIT with running, it’s not really running in the general sense that I’ve described in this post. For example, you could perform HIIT with biking, or jump rope, or swimming; anything to increase your heart rate for the duration of some intervals. The sport of running is more about completing longer distances for a sustained time.
As long as you feel healthy and nothing hurts, I don’t see anything wrong with doing HIIT as frequently as every other day for your general health. I like your approach of gradually increasing the intensity and shrinking the rest periods. Seems good!
