I have a question regarding Training Peaks (Friel's method) and the calculation of Functional Threshold Pace (for running). Here's the full quote...
"Determine your Functional Threshold Pace (FTPa) using either a runner’s GPS device or an accelerometer. To do this, warm up and then run for 20 minutes just as described under “Setting Heart Rate Zones, Step 1” above. Your FTPa is your average pace for the entire 20 minutes PLUS 5%."
My question is regarding a specific part of the last sentence where it says "PLUS 5%."
Does Friel mean the average pace + 5% faster or slower?
