Should I walk in Zone 2?
Should I walk in Zone 2? But try to keep yourself in Zone 2 as much as possible—even if it means walking when you think you should be running. Over time as your body's aerobic conditioning improves, you may graduate to jogging for Zone 2 training.
Why is it so hard to stay in Zone 2?
Zone 2 running is “hard” because most people find it very challenging to stay at a slow pace for a long time. 45 minutes should be the minimum time that you should aim for. Until your aerobic base (and mitochondria) are better trained you will find that you have to run at a painfully slow pace and walk many hills.
