I am lifelong competitive athlete with T1D, understand how you feel, and applaud your keeping fit and active. Diet and exercise are critical tools for proper management of T1D. Whilst you will no doubt find many folks here to speak with, perhaps the most important connection for you to make is with your Endocrinologist. You should discuss strategies on diet, timing, and basal and bolus adjustments for days when you exercise. If your Endocrinologist can’t or won’t, find a new one.
Likewise there is a lot of material on both the Joslin Clinic and JDRF sites that discuss diet and exercise management. IMHO, I would not bother with WebMD.
You don’t mention whether or not you are using a pump or CGM. You might find that these tools make it easier to tweak dosages taking into account exercise, and meal timing, and to continually monitor your blood sugar levels. If you are not using them, you might want to at least explore the ideas and ask your doctor about them.
Even if you choose not to use a pump or CGM, there are simple strategies to employ to adjust basal (long acting insulin) and bolus amounts (short acting insulin) along with the timing of snacks during exercise. Again, I suggest that you discuss that with your doctor.
