Hi Tammi! Glad that you found us!
I used to have to eat 2 bananas in order to go for a 40 minutes run (when I was on Lantus). With the pump, i am able to stay between 80-150 on the run. Here’s how I do it:
One or two hours BEFORE i start running, I turn my basal down to 50%. I leave it on 50% until I am done running. The point of this is that any insulin that goes into is active for around 4 hours. So… if you only turn your pump down when you start running, you are starting the run with your full amount of basal. By turning it down earlier, you can be sure that you have less than the usual basal insulin active.
Also, I try not to run for two hours after a bolus. The remaining insulin from the bolus will make me drop too quickly. I like to run in the morning— so I can even program a basal pattern that turns my basal insulin down before i wake up.
I have found that I rarely have lows while exercising with this routine. BUT I still seem to have highs about 2 hours later. So I think when I stop running, I need to give a small bolus.
