bike 4:39:00 [3] 78.5 mi (16.9 mph) +1010ft
ahr:133 max:164
well I have been sick this past week and the sore throat finally went away, but I am still congested. But I still decided to go ride. I went out to do an easier ride and just go by feel. Well I never really felt tired on this ride as I kept the HR in check. I did Big Ring a couple climbs(inclines) and noticed that the HR did elevate and that it didn't recover as fast.
The one thing that really stands out in my mind is the calorie intake. last week I did bike another 30 miles longer but I must have consumed at least 2x the calories if not more. I tried to restrict the caloric intake this time and I also never felt hungry during the ride.
Conclusion is that at some point between 133 BPM and 141 BPM my body switches from fat burning to burning a much higher percentage of carbs.
I am going to have to make this my regular ride and keep the HR in check until I become more efficient at burning fat. I should still be able to hit the mid 140's if not higher and be burning most of my calories from fat.
