Any Words of Wisdom? - 1st 1/2 Marathon

In about 9 days, I will run my 1st half marathon.  T1 diabetes is such an individual thing so I know "words of wisdom" are difficult.   My big question is, for those diabetic marathoners out there - what do you eat for breakfast? 

The run starts at 7am (which is about 2 hours from my normal breakfast time) ... I know carbs are a necessity of course, but just curious what types of things keep you going strong throughout the race and don't create a lot of "gut bulk"?  Normally I run in the evenings since I start work so early in the morning so I'm a bit nervous.  Any tips?  I'll have myself loaded with quick sugar gels (I generally need to eat about 20 carbs every 30-40 minutes when I run).

I just wish I could run this race worried more about "the run" instead of my blood sugars.  Blah.

I also am a beginning runner. T1D; 62 YO. I have run five half M's in the two years since I started running. All have been interesting and none has been simple from the diabetes control perspective. I use a Minimed pump and CGM. CGM has proven to be a worthless technology. Who needs to know, within a 20% or 30% tolerance, what their blood sugar was 30 minutes ago? Useless. So I dumped the CGM. On shorter training runs of less than an hour, I ditch (disconnect)  the pump. For me, blood glucose drops quickly once I begin exercising, and with the 4-6 mile runs, it tends to stay consistent. For longer runs, without insulin, it begins to rise after an hour or so, so I keep the pump on, and adjust basal doses; say 50% at the beginning, and if BG is ~100 or so, I add 25G jelly beans or a gu, and then I check in 45 minutes. I seem to get it right half the time. Very low BG during runs has been a problem only once or twice: then, of course, the time it takes to get back up is a problem. Often though, it will rise dramatically toward the end of longer runs and then there is that watershed question; do I use a little extra bolus and risk getting low, or do I ignore it and risk going very high (~250+)? I've no answer yet, and I suspect this is individual. Often I will feel keto-acidotic immediately after running...and it often takes at least two hours of extra bolus to get back down to "normal". NOW, I'm thinking of training for a full marathon, and I'm clueless about how to handle that one...

Breakfast? I don't eat before running. A little snack is what I take--a half banana, then Gu or something light in the midst. It's a tricky thing. Blah? This is the challenge of the thing, right?

GeePurrs how did the race go?! i "ran" a half marathon last august and was very lucky to have kept a somewhat steady bs for the majority of the race, until the end where it went a little high. i am beginning to train for another on my birthday of this year. I'm addicted.
