Woke up with a headache again, but much less severe.  Decided that I had to get back to my routine, so I headed out the door to the gym.  Same workout as yesterday.  But I would aim for 183W.  But I missed.  In the first 20′ section, I again found myself around 185 with 5 minutes to go, so I just stuck with it.  Today, my HR average over the last 5 minutes was much higher (6 BPM), but the lactate reading was down to 2.1.  Another message to stick to 183 for training power.

The second and third intervals I did that, but it felt significantly harder than the session on Tuesday evening.  Maybe short recovery?  Maybe time of day? Maybe phase of the moon?
