Not sure what the question is as the intensity hasn’t been defined.
Are the intervals being run at a pace that means the run is shorter than otherwise? Or is this a means to run longer?
Is the pace under aerobic threshold or above?I never do a continuous run, as every run has at least 3 or 4 traffic stops, plus maybe a stop for a pee, drink etc.
Most people who know of Ernst van Aaken associate his method with high volume and slow running. That's partially correct but his runners did a lot of interval work. But it was not gut busting hard running. A lot of it was at slower than race pace. He wrote that children playing was a natural form of interval training. His son told me that he and his dad ran ten kilometers after work each night in an hour. But it was not a steady run at 6:00 per kilometer. It was done with faster runs with walking breaks.
