Well, any sign of progress is to be welcomed so I am going to take this MAF Test result with open arms. Certainly the cooler weather had a lot to do with it, but I am not certain why my mile pace gradually got better. My theories range from I had eaten too soon to the start of the run, to I got faster as the night got cooler, to finally that it was the fact that I got into a rhythm and topped exceeding my MAF heart rate and then slowing down to get it back on track. The other good sign is that I am gradually increasing my Time In Zone which I am taking to mean that I am able to run at a more stable pace. Let’s see what next month’s test brings.
