Hi guys been gone a while, really busy at work and at home. I've got a question and every one I've asked hasn't given me a reasonable answer. I ran a 100 mile race july 15-16 in vermont, checked my sugars through the entire event and they were fine. I didn't take any lantus the night before because I am still honeymooning and I have dropped to low during long runs with it on board. So I finish the race and go back to my hotel and sleep for a few hours check my sugar when I get up its 215! I haven't eaten since 0400( it's now 0900) I knew my BMR must be really running high so I didn't want to take any humalog untill I got to the race award breakfast. Post breakfast it was 240, 3 units of humalog brought it back to 160.Any ways why do ya'll think it was so high after the race? I amost never have sugars like that even with out lantus, an on days I don't run I've only gotten as high as 200. I chased my blood sugars for a couple of days like this. Any help would be greatly appriciated. Thanks claire.

It could be one of two things. The first could be you are honeymooning less and less lately. Or the second could be you hit a low where your liver decided to dump a large amount of glucose into your bloodstream and then it's causing you to peak really high. Those are my best two guesses and without knowing your readings every minute of the race via a CGMS unit, I can't help you more.

Do you normally go high after exercise? There's at least five members here who go high during/after exercise no matter what they do...

I go highish after hard fast exersize, like a 5 mile speedwork run. But trust me this 100 miler was VERY slow. Usually after long runs I am normal 80-95 ish.

My theory (and this would be very hard to prove since I somehow think you don't run 100 miles often?) is that your body is reacting to this stress by dumping glucose from the liver (flight or fight response).

Hmmmm...Then again, I'd have to think that after X miles, your liver should have dumped all its reserves...But it could be a rise induced by hormones, but again, you need a glucose reserve somewhere, right?

Great. Now I'm going to be thinking about this...

Hi Claire,
The only thing I can surmise is that you may have had a low and had a reaction to it. How often did you check your blood sugars during the race. Normally with me when I exercise I get lows and then a possible high if I don't correct in time. I haven't heard of people going high after exercise. Do you take the exercise into account when giving your insulin?. If so it might be that your adjustment was a little out. When I exercise I always reduce my basal beforehand and during. Hope you can sort it. Michael
