Long Runs and Type 1--Nutrition During Workouts
I'm interested in hearing from anyone with Type 1 who does long (1 hour plus) runs or other cardio workouts. I am currently preparing for a half marathon, and will be doing marathon training after that. My biggest problem is getting low during the run. So far, I take my pump off during the run, and bring my Dexcom so I can watch my blood sugar numbers. I take one or two glucose tabs whenever I get below 90 or so. The problem is, I have to go through so many! Last week on a 12 mile run, I went through 20 tablets, and was still getting pretty low by the end. Maybe I need something more subtantial, like gels or bars?
What kind (if any) of nutrition do you use during a long workout? How many carbs, how often, what form? Pump users, do you keep yours on during exercise? If not, is there a limit to how long you can go without needing it? Anything you could share would be helpful...

Hi Emily,
I too am a long distance runner and a T1. I'm not on the pump. I try to run all of my long runs in the mornings. I don't take any short lasting insulin before I run and I try to start my runs a little high (over 120 but under 200).
When I run in the evenings I make sure to be at least 4 hours with out insulin.
For lows I take dried dates - a higher GI than sugar. I don't think you need gels for any thing under 10 - 13 miles. and the gels don't do all that much for your BS.
If I were you I would disconnect you pump a few hours before you run and start a bit high.
I don't eat anything during a run and have had very bad experiences (including almost stopping a half marathon because I mistook dehydration for a low). Before I ran a marathon I ate 1 banana a half hour before the start.
