Reading before a run

4 to 5. I run in the morning just on long-acting, so don't need to monitor.

I prefer to do cardio exercise at around 6 with no insulin on board.
This means I have not bolused for more than 4 hours and have suspended my basal on my pump for an hour beforehand.
If my blood sugar is above 8, I am too sluggish and have no energy. If it is in the 5s or lower, I risk hypoing.
