I am a type-I diabetic and I am in the process of training for a half-marathon. I would like to solicit any advice that type-I diabetic marathon/half marathon veterans may have. I am currently using a Medtronic Minimed pump with novalog insulin.
I am having a bit of trouble regulating my blood sugar while running. I tend to get low during during any run for 3+ miles. I usually eat before running, but this sometimes complicates things. I have a busy work schedule, so I usually run at 9-10pm.
Does anyone have suggestions on how to better regulate my blood sugar during runs? Do you veteran runners bring any particular snack with you that you can eat during a run to prop up the blood sugar?
Hello, Are you taking a bolus injection before eating a meal before running? How fast are you running? (Note-The faster you run the quicker your blood sugar will drop, and this rate will vary with how trained you are and how lean you are.) As with all diabetics, what works for me may not work for you. However, I have found the 'goo pack' by the brand name of 'Carb-Boom' to work very well. It has 37gm. of carb but only 3gm. of sugar. I have used these several times on very hilly runs that lasted more than 4 hours (up to 6 hours) I have never used a pump (nor will I) b/c it seems that most people have to remove them to exercise over long periods of time. I would suggest asking your doctor what's up (good luck with that.) At least try to get your doctor to point you in the right direction. Even with my extremely brittle type 1 I could easily run at least a 10K before I ever had to worry about hypoglycemia. Good luck and don't give up! Ralph
I almost forgot... I Carb-Boom/hour would keep my blood sugars between ~90-~115, and that was with some real hard running! Also, keeping hydrated (not over hydrated!) helps keep the blood sugars within the normal ranges.
I run about and 8 minute mile if I'm doing around 6 miles. I use an insulin pump and I do leave it on while running. I don't always eat before and I end up having highs by the time I'm finished much of the time. Thanks for you advice I'll try the Carb-Boom. It sounds like you do a lot longer runs than I do.
I trained and ran for a Half-marathon last fall. During training, I was usually okay if I ate something right before I left, and then had some Gatorade or some sports drink with carbs in it in case I went low during the run.
For the actual race, they handed out these energy-gels that seemed to keep my blood sugar up during the race. Afterward, I made sure to eat something too because I usually have more of a problem with a delayed low when working out.
