DN’s Running and Other Mishaps Thread


Of course. So you think that was all the difference? Here was my thinking about taking the carbs around mile 2-3 without knowing I need them… Sometimes I really don’t need them. Depending on everything that’s in progress as I head out the door, 15g of carbs taken unnecessarily can leave me at a less than ideal ending blood sugar. Sometimes those really give me a hard time for hours to come after I’ve finished my exercise. So my thinking was that yesterday’s run was relatively fresh on my Levemir dose whereas the one on the day before was past when my shot was due. I absolutely agree that yesterday’s run was more intense, but I know my blood sugar starts to push up at my next dose time. I was attributing at least part of the difference in glucose tablet consumption to that timing of Levemir. Is that wrong? Because somewhere in the back of my mind, I’ve been trying to avoid having to take a run on a fresh shot… but maybe that’s not really a thing??


Okay. That makes sense… but if I need them. I don’t want to take them if I don’t need them— That leaves me with a mess.


Since Levemir is not a fast acting insulin, it takes a bit of time to ramp up and to ramp down. If you run right after taking your 2nd Levemir dose, it’s probably about the same as not taking it, at least for a while. But if you are going on an hour long run, it would start to kick in before your run was over.

Yep, there is a big difference in timing. Just 15 minutes can make the difference in a spike or good BG.

Testing as you run will be a big help.

Was yesterday on the treadmill or road?


No, don’t take them if you don’t need them! If you have eaten within 2 hours you still have enough carbs for your body to use.


So let me clarify… because either I’ve misunderstood something, or I’m being unclear. The other day, you mentioned to me that getting in a run just around the time I should be getting my next dose was somewhat like creating the zero basal effect— or, at least, that’s how I understood it. As much as is possible, I’ve been trying to keep that in mind when planning my runs. I interpreted the big difference in how many carbs I needed between the last 2 runs as, in part, a result of the difference in Levemir timing. Here were the two schedules:

3:00 pm Levemir DUE (I usually take 8 units around 2:30)
4:10 start run—5.2 miles. 45 min.
Starting BG 91. Ending BG 107.
5:15 pm Do 7 units of Levemir
0 glucose tablets during run

3:00 pm Levemir due
3:15 pm Do 8 units of Levemir
5:45 pm start run—Started at a 115, did my half mile warm up, did 4.9 miles in 40 minutes, and ended at a 126.
Had 3 glucose tablets at start of run and 6 more at 2.5 miles

The way I saw this was my first run took place past the time my Levemir was due, whereas the second took place on a very fresh shot. My interpretation of that is that one run had less basal than the other, and I absolutely see that rise if I’m late with a shot, so what does that mean for me in regards to my basal status?

Am I making sense??


I did not understand what you meant when you said you were fresh on your Levemir dose. I thought you meant you had just taken it. I see here that it was 2.5 hours, so yes you had basal for this run, which was unlike the previous day.

What I meant is that if your basal is due at 3pm and you take it and immediately start running at 3pm, your basal hasn’t really started yet.

So your numbers here :arrow_down: make total sense:

On Monday you had no basal, and needed no carbs. On Tuesday you had basal for the run and needed 9 gtabs.

So all of these things line up with expectations.

I think the only misunderstanding is that I did not know that Tuesday you took it 2.5 hours before starting. I thought you had taken it right before starting.

Are we on the same page now?


We are, and my mood has just taken a turn for the way better. :hugs: I dislike thinking I understand something only to find out it’s not real. Not the case. I only miscommunicated something. I can deal with that.

New understanding. New tool. I’m gonna go smile at somebody. :grin:


Check out the only thing I brought out with me to pick up my son today. That and 6 tubes of chapstick, but there’s hope for that yet. :grin:


That is downright sexy!

Yep, that is my next project for you.




So I did 1/2 mile at 9:15 pace, then the three sets as written above (3/4 at 8:30 and 1/4 at 7:30) and then I finished with a 9:15 pace cool down. RPE was like 5… I felt so good as I finished the three sets that I had to go back and make sure I hadn’t missed one.

About my BG… I was going to start my run at around 9:45 this morning. I got home from volunteering, and my BG was around a 75. I had about 30 minutes until my run, and I was tired. I figured I would have a small cup of coffee, and if it looked like I needed to start earlier, I would just do that. The coffee didn’t do anything to my blood sugar, so I brought my banana over with me and ate it PLUS 3 glucose tablets right before starting. My starting BG was an 82. Because I was running in the morning, like we discussed yesterday, and I knew my Levemir was relatively fresh, I went ahead and had 15g of carbs at mile 2.5 even though I didn’t feel any symptoms of a low. I finished my workout at a 98. Within about 10 or 15 minutes, I saw I had risen to a 118 so I did 1.5 units—- and stayed between 85 and around 100 the rest of the afternoon.


Perfect, right? Like some kind of spooky magic trick!

You are doing great with these, and your BG stuff is coming together exactly like we want. Awesome stuff today!

Was this on the treadmill? 8.0 mph on the 1/4 mile intervals, right?

All of this is going well. The week after next we will start to ramp it up.

Did you ask the guys at the running clinic about incline work? Is that okay for you?

Still doing your stretching and core, right?


Yup. :slight_smile:

Completely forgot. I can send him an email.

Yup. :slight_smile:


That might be the fewest words in a DN post ever!


Won’t let it happen again. It was terribly boring to write. :grin:


It looks like it has been a phenomenal couple of weeks for you. You did the running clinic, you are running without pain now, you are nailing every single one of these workouts, and your BG has been outstanding! Great stuff, right?

Oh, quick follow-up. The running clinic was supposed to give you the name of an orthopedist to look at your MRI. Did you hear from them yet?


It’s in my email. :grin:


Today was easy and short. I was supposed to do a 25 minute easy run at 10 minutes a mile, and I did. I had a coffee about an hour before starting and watched my blood sugar just continue to hang low. I had a banana about 30 minutes before starting, prepared to jump on the treadmill at first sign of a climbing blood sugar, but, again, it continued to just hang low. So I ended up having 5 glucose tablets with a starting BG of 85, and that held for the duration, giving me an ending BG of 76. It was a very good day, and I look forward to my run tomorrow. :star_struck:


I’m a little low right now and a lot of sleepy, but I want to get this down before I forget it all.

I had a wonderful run. My starting BG was a 118. I had a coffee and banana about 30 minutes before starting because I was at around a 65. I figured I could take a few glucose tablets at the start if need be. I did my full 19 units of Levemir at 6 am, and my run was at 11:45 am. Anyway, I decided to have another banana before starting my run, and I STILL needed 15g of carbs at mile 2, ANOTHER 15g of carbs at 2.25 miles, ANOTHER 16g of carbs at 3.1 miles, and 8 more at 6 miles. So that was a whopping lot of carbs, BUT my blood sugar, according to my Libre, never went above a 134 or below a 96 (Dexcom showed a little spike at 100 and dropped to 58– but I don’t think I was actually that low)…

That’s confusing, I think. What I was trying to communicate is that I had a starting BG of 118 and ending BG of 125 for a 60 minute 6.5 mile run. I had a small banana just before starting and then 40 grams during my run. Because I had had so many carbs in all of that, I decided to do a 1.5 unit bolus when I was done, and then when I saw I was starting to rise about 30 minutes later (this was a 130 on the Libre, but no fingerstick), I decided to do another 2.5 units. I overshot. Big time. One banana, one yogurt, 2 Welch’s fruit snacks, 25 crackers, and 4 glucose tablets later, and I’m all sorted out. :smiley:

So I feel like I did a really good job getting myself through a long run without having to run my numbers high and without crashing. Then I think I just wrong. I was afraid all of those carbs were going to really make me take off, but my Libre was only showing a 130, and that may have really been a 110… and I gave myself 2.5 units of insulin after an hour long run.

Okay. I’m still happy. :hugs:


My 2 cents is that it sounds like you handled it really well. Not that it worked perfectly, but that you made reasonable choices and handled everything sensibly as it unfolded. You are competent.
