Perceived exertion test compared to heart rate zones. Hadn't run since Sunday with Steve out of town until late last night. The Gorge Waterfalls 50K race is in 48 hours.
0.1mi warmup walk. 1 mile at Zone 1, perfect 50% of calorie burn was fat, 11:30 pace. THIS IS AROUND WHERE I WANT TO FEEL FOR 9 1/2 HOURS SUNDAY OR I WON'T MAKE IT.
Then... 1 mile at Zone 3, pushing over anaerobic threshold in the last 1/4 mile. only 27% of calorie burn was fat as an average, 10:08 pace. This is what makes you hypoglycemic in an endurance race! DO NOT DO THIS!
Ended with 0.25 mi cooldown walk. Heart rate recovered quickly, which was great to see.
Legs feel good. Calves slightly tight.
Immediately had 2 scoops of L-glutamine powder when I came in the door along with a bagel to start putting in carbs for the slow 48-hour carb loading.
