Like it was suggested by Ken, it looks like you have pooled insulin in your body. I call it “Insulin Latency”. I think I may have picked that up from somewhere like Dr. Bernstein.
I run 4 morinings a week and don’t use a pump so my advice may not be very useful for you.
I sort of have my insulin usage down to a an in-exact science. If my blood sugar is 90 when I wake up, I take my long acting Lantus, (4 units) and one unit of Humalog (This covers what’s known as the “moring effect”. I’m pretty sure you know what that is.). Then I go running within 15 minutes. When I return after about a 30 minute run, my BS is usually around the same amount, 90. If not, if it is low, I take glucose tablets to make up for any low. IMMEDIATELY!
But, if I wake up and my bs is high, I take the same Lantus, and Humalog on a sliding scale. It also depends on what food I had the night before. I never eat before going for my run. I prefer to let the “morning effect” take over for what I need for energy. It seems to be quite consistent. (Man, this is getting confusing, isn’t it?)
When I run, I find that I need less insulin for my breakfast as well. That would seem to make sense, wouldn’t it? And I tend to eat just about the same thing for breakfast every morning so I know what kind of dosage works. (Oh yeah, I tend to favor 4 eggs, scrambled, and a banana for my morning petit de jeune’.)
Any way, this works for me along with eating a low carb, paleo-type diet. Of course I’m not perfect with the diet. I tend to cheat a bit. I love cheese and crackers, prefering some sort of strong swiss cheese and red wine to go with it. But that’s me. I don’t recommend this for anyone else. Unless of course it’s your desire as well.
So, I hope this little missive gave you some idea. It really works for me and my Endo says I’m just about the healthiest Type 1 he knows. And he knows a lot of them. One more thing, my last A1C was 5.4. I may be a bit more obsessive than most with my control but it keeps the clouds out of my head.
Best of luck with your excercise routine. Keep at it. It’ll come aroudn with a littel more trial and error.
P.S. I hate to be the “bad guy” but, you really shouldn’t be eating a bowl of pasta if your diabetic. Pasta is something best left to non-diabetics who don’t over eat. Sorry for the bad tidings.
