This week, you don't have a big lift before your endurance training. Don't take that to mean I'm letting you get off easy. If anything, an endurance-training-only day means you should push even harder today.
Your goal should be to increase the mileage or decrease the per-mile time from last week's endurance workout. Push harder and do better every single day.
Don't forget to write down how far you went and how long you worked!
