It’s essential to listen to your body with this one. Ideally, as a beginner, your runs should be well spaced out throughout the week, and you should try not to run on consecutive days. A good example would be to run on Tuesday, Thursday, and Saturday or Sunday (not both). It’s much better to keep things light at first and gradually build up rather than risking potential injury, burnout, and lack of motivation. The main things you should be focusing on are the health benefits and enjoying the process.
