Calculating my Functional Threshold Heart Rate

TRAINING PEAKS explains "Your threshold heart rate will be the average heart rate from a recent intense race or very hard interval from a training ride, where you spent 45-60 minutes in duration at an all out effort."

Using a Polar FT7 Heart Rate Monitor I rode 60 minutes hard along the canal service road between Villamartin and San Miguel six times.  My average speed was about 31 km/hr and my average heart rate was 138 bpm.
