Awesome! Glad to have you here! We have several runners here.
Just curious, with your exercise override, your basal is basically just off, right?
I generally turn basal off for the entire run, so with Loop I was setting a crazy number to ensure it would be off. I ended up just going back to the normal PDM because it was easier for me. Plus bolusing was much easier from the PDM than it was from phone. Touchscreen is not easy when running.
Does your BG ever rise from adrenaline spikes?
I have suggested chocolate milk 10 or 1000 times here. 
You mean a snack right? Not a meal?
What time of day do you usually run? I mean, is it like after a meal? Like after breakfast/lunch/dinner?
What do you use to fuel during runs?
Is that still a problem or concern? If it is, I have some suggestions that might help!
No, I am not on Strava. I just work with my coach through TrainingPeaks.
