I ran 10 miles today. It’s possible I did this when I was young, but I have no memories of doing it, so there’s some chance it’s my first 10 mile run ever, and I’ve been singing about it for hours.
I ALSO took down a whole lotta numbers during my run. Really, I did it because I find this stuff fascinating, but there’s also been discussion about CGM during running, so I was just doing my part. I do have to say this would’ve looked really differently had I had a fast drop in blood sugar. If I had taken this down on Monday, I’m sure it would be much more dramatic, but I do think this is pretty representative of how it looks on slowly dropping blood sugar.
Also, I did try two different types of carbs during my run, as this has been something I’m just learning about, and it didn’t surprise me at all the difference. I tried a CLIF gel and a CVS liquid glucose shot. The CLIF gel consists mainly of “organic maltodextrin”, and the liquid glucose shot was … dextrose???
Other tidbits: I did not repeat the same mistake today and avoided doing any boluses before starting. My blood sugar had been stable at around 85 for hours prior to starting. I did it again with the coffee though… and had one just before starting, but I decided I’d just ride the high. I know I’m not supposed to be doing that, BUT it worked out well. So it’s almost like it never even happened.
Starting BG: 85
Half mile: BG: 79
Mile 1: BG: 85
Mile 1.5: BG: 79
Mile 2: BG: 74
Mile 2.25: CLIF gel (~23g)
Mile 2.5: BG: 60
Mile 3: BG: 58
Mile 3.3: Glucose Liquid Shot (~15g) — symptomatic. Needed a kick.
Mile 3.5: BG: 64
Mile 4: BG: 73
Mile 4.5: BG: 78
Mile 5: BG: 82
Mile 5.5: BG 89
Mile 6: BG: 80
Mile 6.4: CLIF (~23g) — decided to use this since I didn’t need another fast boost but wanted a slower acting carb??
Mile 6.5: BG 75
Mile 7.2: BG 74
Mile 7.75: BG 78
Mile 8.3: BG: 73
Mile 8.8: BG: 73
MIle 9.3: BG: 74
*1.5 units
Mile 10: BG: 72 (done)
*.75 units
BG was already at 96 about 5 minutes after finishing, so I added another unit and had a banana a few minutes later. I had some chicken soup and salad maybe 20 minutes after that and really have kept an eye on things. It’s been a lovely line but with a tendency to drop. I decided on a 75% temp basal overnight just so I don’t have to eat sugar tabs all night. 1 hour and 37 minutes was my total time, and my RPE was a cool 6.
Now for the part you don’t need to see, @Eric. You can just not bother.
Here are the BGs up against my Dexcom values and Guardian values. And then it’s to bed…
I’ll list the values as BG (meter), D (dexcom), and G (guardian):
Start: BG: 85 D: 82 G: 73
Half mile: BG: 79 D: 82 G: 72
Mile 1: BG: 85 D: 85 G: 72
Mile 1.5: BG: 79 D: 84 G: 75
Mile 2: BG: 74 D: 77 G: 74
Mile 2.25: CLIF gel (slow acting carb)
Mile 2.5: BG: 60 D: 67 G: 68
Mile 3: BG: 58 D: 58 G: 55
Mile 3.3: liquid glucose shot (fast acting carb)
Mile 3.5: BG: 64 D: 53 G: 48
Mile 4: BG: 73 D: 57 G: 41
Mile 4.5: BG: 78 D: 63 G: 44
Mile 5: BG: 82 D: 70 G: 51
Mile 5.5: BG: 89 D: 74 G: 57
Mile 6: BG 80 D: 75 G: 61
Mile 6.4: CLIF (slow acting)
Mile 6.5: BG: 75 D: 74 G: 62
Mile 7.2: BG: 74 D: 71 G: 60
Mile 7.75: BG: 78 D: 68 G: 58
Mile 8.3: BG: 73 D: 67 G: 55
Mile 8.8: BG: 73 D: 65 G: 53
Mile 9.3: BG: 74 D: 65 G: 53
Mile 10: BG: 72 D: 64 G: 52
And the 5 minutes after finishing… when my blood sugar really took a quick jump: BG: 96 D: 66 BG: 47
Not as exciting as it was while gathering it, but a great day all the same.
