Many people associate progression with speed. However, easy running serves a different purpose: developing your aerobic system, improving your recovery, and preventing injuries. ✅ Easy running corresponds to 65-75% of your maximum heart rate (MHR). ✅ It's a pace at which you can talk without getting out of breath. ✅ It may seem very slow at first, but your speed will naturally increase with training. If your heart rate is stable in this zone, then your pace is perfect, even if it seems slow!
