I could only do three sessions, not four. It was meant to be 7/7 on/off but I could only manage five minutes for the fast part. I felt I really needed to focus on making my strides longer and pumping my arms a bit to get the speed going. But maintaining that for any length of time beyond 5km or so seems really daunting.
