I survived my first encounter with intervals. I was supposed to ride in the “tempo” heart rate range for three sessions of 5 minutes each.

The computer beeped at me for having my heart rate too high, then too low, then too high. It was quite difficult to hold it consistently in the range, but I tried. I guess it worked ok.


I’m supposed to do the same thing tomorrow, except in the more difficult “threshold” zone, so that should be a good time.
