I happened to have an EMT and a diabetic at dinner. The diabetic had his meter with him. I quote " absolutly 911 levels". (single digits). Some ice cream brought me back.
I've been type 1 and biking for the past 8yrs. It can be a challenge before the ride, during the ride and after the ride.
Then comes the day off after a strenuous ride and your body metab is going crazy because it's still cranked up but your insulin dose and diet remains the same. In short, (for me) it's like exercising when you are not. I've only had one 911 low and that was following a fast 30 last year and I didnt eat enough or quick enough to adjust, it was early in the season.
