Power (Watts): 191
Average Heart Rate: 142
Average Cadence: 71

Test week continues with a non-easy day. The main set consisted of two 20 minutes efforts at 80% of my newly estimated Critical Power of 240 watts. Since there were two equal efforts, I decided to use a lower gear for the first so my cadence would be faster, and then a higher gear for the second which would slow down my peddling. My thinking was that my heart rate would drop during the second interval. I was wrong.

Power (Watts): 201
Average Heart Rate: 146
Average Cadence: 77

Power (Watts): 201
Average Heart Rate: 149
Average Cadence: 67

As you can see, during the second interval, my cadence dropped by ten revolutions, more than I expected. However, I maintained the same power for both intervals. The heart rate? Well, it actually went up by 3 bpm during the second interval! Not much, but it move in a direction I was not expecting. And the funny thing was I felt I was not working as hard during the second set. I thought my breathing was not a labored.

Food for thought.

Now, on to Thanksgiving dinner!
