Frustrated that your BGL behaves early in a session… until it doesn’t?
It’s a pain in the a**. I get it.
And it’s incredibly common in the people I work with.
However once you understand why, it actually makes sense.
Your muscles run on glycogen (carbs) first.
As those stores start dropping — especially with increased insulin sensitivity — your BGL can follow.
That doesn’t mean you’re unfit.
It doesn’t mean you planned badly.
It means you’re training with type 1.
Training with T1D isn’t just discipline and carbs.
It’s understanding how your body works.
Understand the why.
Then structure the how.
*of course BGL will also vary based on factors such as IOB, whether you have eaten, temperature, etc.
