Hi – I’m a Type I on an insulin pump. I’ve been a Type I for about 42 years. My A1c ranges from 5.4 – 5.8. I go loaded with carbs when I ride the bike (Cannondale Synapse Hi-Mod 1). I carry about 40 of the 4 gm carb tablets, and I wear a wrist bracelet with my name, condition, phone numbers, etc. And, most importantly, I carry a blood glucose meter (if I have any question, I stop and use the meter). I can get all of this equipment, along with my tire accessories, in a simple under the seat pouch. Just a word of advice to older Type I’s: as you age it may become harder to “feel” the lowering of your blood sugar. I can generally feel it on hills when I need a burst of power. But, on those days when you miss (and I have), you can be in trouble very fast – cell phones don’t help in this condition. My area is heavy with bicyclists, and at least one headline a year describes a tragic roadside scene involving a Type I. I’ve noticed that many of my Type II diabetic friends have relatively high A1c readings, and indeed they seem to have a much lower probability of very fast, sometimes un-recognized, blood sugar drops under heavy exercise. But, those of us that are Type I and tightly controlled have to be very careful. My advice is to ride with an overabundance of caution, but do ride. It is hilly in my area of NC and I ride between 20 – 45 miles, 4 times a week, at about 15 mph average. My best wishes to all of you.
