Success! Did 9 miles this morning starting at 122 finished at 156! Not a record time but for now I'm focused on maintaining level blood sugar. Amazing how much better I felt running with steady blood sugar.

I use Skin-Tac and place the Dexcom CGM on my side just above the belt line. That seems to be where it lasts the longest, e.g. 10 days to 2 weeks. The skin and the CGM tape flex together there whereas the skin on the arm and stomach can stretch which might loosen the CGM tape. Also the CGM is somewhat shielded from direct water spray in the shower. Whatever the reason, the skin-tac and this location always give me the longest CGM life.

I haven't run using skin-tac with the Omnipod. It usually sticks ok to bare skin for its 3 day life.

There are a lot of CGM users who swear by Opsite Flexifix (http://www.smith-nephew.com/professional/products/advanced-wound-ma...) to tape down the sensors. Others go subterranean and use Skin-Tac (http://www.amazon.com/Skin-Tac-Liquid-Adhesive-Barrier-SKIN/dp/B008...) to help with adhesion. I often think about taking crazy glue with me on long runs, just in case something starts to detach (CGM or OmniPod).

thanks for the ideas. i was thinking of using a sock with the foot cut out so it is worth a try. :)

I have considered, but not tried, using K-tape to hold on a sensor. It seems like something designed to last through a marathon, that just might do it.

But as I said, I haven't tried that.

I have bought dollar store tube socks, cut off the leg part so it is just a sleeve, and pulled that over my arm and over the sensor. It works, but for long runs you really want to make sure you lube up under your arm to prevent abrasion.

I suppose you could use arm warmers instead, but I haven't done a marathon recently in cold enough weather for that.

Good luck.

Alright everyone, I need your advice. I received my CGM's and attached one to my arm Friday afternoon so I would have it for my long run on Saturday. It peeled right off while on my run. It worked well for about 8 miles and seeing what my blood sugar was doing but by 10.5, it was peeling and by 12 it fell off. :( Does anyone have suggestions for keeping it on? Also to compound things, I fell on my tailbone about 10 days ago. It is excruciating. My marathon is 3.5 weeks away and do not want to back out. Any advice?

Hi Brian, I wonder if the insulin you are using peaks for you later than the medical folks predict. If so, you might have more insulin on board than would be typical even three hours after a bolus. Also, I experience similar drops with running. It helps me to reduce the basal rate to 15% or less at least one hour before running. If I forget to do this, one Power Gel about 30 minutes into the run helps stabilize the sudden drop. Hope this helps you. Keep experimenting -- something will work!

Today I was hoping to go for 6 miles. I ate a late lunch and bolused 3units at around 2:20pm. At 5pm I went for a run with my blood sugar around 250. 30min later I was 99 with double arrows down. I'm starting to feel like I need to be 400 in order to go for a run. Apparently, I'm extremely sensitive to insulin when I run.

Those are my chickens in the background in case you were wondering :)

I agree that ups and downs are rough! I generally try to "run" (ha ha!) as flat as possible, rather than running up, burning it down and then boosting it back up. I think that ideally, you can sort of feel out how many carbs you burn off in say 3 miles and sort of aim for that during training. If it works, that usually works out very well for races, as there will be fuel stands every few miles and you can just use their goodies. To me, it's easier to keep nudging it to stay flat than to run up and down. It doesn't always work but it's fun to keep at it.

A lot of times, I sort of use the basal rate as a BG Gas Pedal and sort of nudge it up and down with that. If I kill the basal to 7%, even if I'm running, I'll usually see it start to ooze up. Then I turn it down. And up and down and so on until the race is done. Sometimes, I can space out 5 or 6 miles playing with my BG and trying to get it to behave...

Exercise is indeed very important. I think for now I'll keep refining my strategy as best I can to until my BG is more steady on my runs. The ups and downs can be brutal (I did eat a gel when I was at 160). I am glad to have gotten the mileage in. It's helpful to have a CGM on runs although when I had a Dexcom it never worked for me when I ran. The enlite sensor has been much better when it comes to exercise.
