It’s Kim, right?
Glad you could join us here!
You have a number of difficult challenges. So you don’t have any idea what time the exercise sections will be? Do they not give you any kind of schedule or anything?
Is it possible to ask for an idea of what time you will be on the bike?
Since we don’t have much time to work with here, I can start with a few very general rules. A lot of these will take time to get customized to your body.
First, no IOB. If at all possible. Since you don’t have any idea of time of the spin, I think skipping breakfast might be wise, if it is something you are comfortable with. OR getting up very early and eating breakfast well before you start, like 6am.
Second, for anything over an hour, I have no basal. No IOB, no basal. And this also somewhat depends on intensity but I assume you will be working through different zones.
I would assume they won’t make you spin right after lunch, right? That would be cruel! So I am going to guess 10 or 10:30 will be your first spin, and then lunch. And the second one later in the day.
So for your lunch, hit your bolus as soon as you get off the bike from the first spin and also turn off your basal to minimize IOB for the second spin, which I am guessing would be an hour or two after lunch. A smaller bolus and smaller lunch will be your friend there. But try to bolus as soon as possible so you have less IOB.
For carbs, do you ever use gels? Those are easy to get to, small, quick. GU brand gels are good, or anything like that. Transcend makes a good one also, but those are hard to find in stores, I think you need to order them online. I wish we had a few more days.
How comfortable are you riding high or low? Overall, if you are okay with a bit high, a general lowering of your basal for the whole time 9-6 would be good. But I think 0% basal as soon as you bolus for lunch would be smart.
How are you for testing on the bike? Can you do that at all? I can help you with some stuff I use when running, for your future. It’s all about strip management!
Do you have CGM?
And what type of pump are you using?
Anyway, sorry, lots of questions. See if you can get some details on the schedule. That would help us a bunch!
