Not outdoors and not using Sufferfest but perhaps still valuable information for some of you.
:male-scientist: Estimation of Aerobic threshold (AeT) using DFA-alpha1 while monitoring Core body temperature.
Purpose of this workout is to establish your current aerobic threshold using DFA-alpha1 (0.75, HRVT) while also monitoring your core body temperature. Feeding the data into Runnalyze or using Excel you can then estimate your heart rate and power at which you cross the threshold. Knowing these values and staying well below them helps you to keep your easy workouts really easy as they should be. The slightly extended length of the ramp also allows you to find your anaerobic threshold which you should exceed for your hard workouts (0.5, HRVT2). see this article published by Bruce Rogers et al.
I used ‘LetsView’ to project my android screen onto my laptop and recorded my Wahoos’ screen which I mainly used for Core body temperature monitoring and later added to the video. I used Zoom screen recording to record the whole thing. The FatmaXXer app for android helps you to monitor your DFA-alpha1 in real time. You can either use Garmins fit file to visualize data in Runnalyze or download your FatmaXXer data and do it in Excel. In order to record reliable data you need either a Polar H10 (or similar) or a Garmin dual.
