I disagree with the idea. I run regularly, usually 40K per week, I tend to run 3 or 4 times per week. The body needs regeneration, muscle/tendons microdamages need time to heal, depleted reserve of glycogen needs time to restore. The risk of injuries will be higher. Without resting intervals stamina goes down, so consecutive runs will not be as strenuous as should be to build better endurance.
