A.M. Did my 3 mile tempo run uphill. Was feeling tired from the start. The splits were 5:59, 6:07, 6:17 - total time 18:23.5. I have had this feeling before. Probably a combination of running really hard on Saturday and accumulation of the lack of sleep. I am suspecting that feeling means high cortisol levels. I can tell my blood pressure, my weight, my pace, and my heart rate by feel fairly accurately, why not cortisol levels with some training? This is actually an interesting idea - if you trained a mathematically minded athlete by measuring various parameters of his body that could have sensory impact and then telling him the values, he might be able to observe patterns that a scientist might not be able to with all the modern equipment, and suggest experiments that could lead to scientific breakthroughs.
Afterwards ran with the kids. Total of 12.7 for me. Benjamin did 6, Jacob 1, Joseph had a sore hip flexor, too sore to run, probably a growing pain, Jenny and Julia ran 2.
P.M. 0.3 with William.
