Endurance athletics don’t necessarily mean low blood sugar or less insulin.
I’ve always been an active person, but I’ve never taken on an endurance activity that lasted more than a few days. Before the trip started I assumed (with my endo and dietician) that my insulin requirements would dramatically decrease. I imagined being on 0.1 unit of insulin an hour and barely bolusing for food. I’d never see a high BG and I’d come away from the trip with the lowest A1c of my life.
Oh boy, was I wrong.
Have you ever seen a blood sugar in the 300s? Yeah, I’ve seen plenty.
How about the 400s? Yeah, me too.
Ever tipped the scale into the 500s? Certainly didn’t think I’d see that this summer.
I thought I’d left the days of crazy-high blood sugars behind me, but they happened. I cycled and cycled and cycled and they kept happening. It took until the halfway point before I finally got a grasp on my correction factor, food boluses and started predicting those sneaky liver dumps. Long, flat rides meant a higher likelihood of lows. Long, hilly rides meant lows during the climbing sections, highs during the flats and a nice liver dump in the middle of the night to sky-rocket my BGs.
