I find it useful to remember that the Libre is showing me roughly what my BG was 15 min ago.
I tend to ignore the comparison with BG but use the arrows to head off any hypers and hypos.

I hope that it helps with the half marathon and look forward to hearing how you get on.
 
Interesting that your Libre is showing higher readings than finger prick test. Mine has only done that once (in 8 sensors), and it was showing a 9.something when finger prick was 5.something. Needless to say it went back, after a few days of iffy readings, and Abbot replaced it.
 
4.2 vs 3.8 is pretty much identical in my book! I would treat both.

It showed 3.9 earlier today - checked against BG meter - also 3.9! 🙂 That'll do me! Every test I've checked against the meter has been spot on, certainly as close as I might expect when testing the same drop of blood twice, or two fingers at the same time, or same blood/two meters (if you get my drift!)

I expect the novelty will wear off a little, but at the moment I'm interested to see what actually happens during all those times when I wouldn't normally have tested. Things were remarkably level overnight, then started to rise as soon as I got up (thanks DP!). Peaked at 9.5 during my run, despite the fact I'd had 7 units of not-so-rapid 90 minutes earlier for a single slice of Burgen (eaten 45 mins after injecting, and 45 mins before the 9.5). Currently following what my somewhat carby lunch is doing to me 🙂 Here's the story so far:

7 units for one slice of burgen! 😱 It's only got 11g carbs.
 
Odd isn't it, 1 unit per slice for me. Sounds like you get the DP fairly bad.

I think it must be a combination of liver dump and insulin resistance early in the morning, yet I was perfectly steady overnight with no exogenous insulin at all. 7 units was probably 1 unit too many, but even so I had 6 units for a burgen ham and branston sandwich, banana, Onken cherry yoghurt and two pieces of 85% chocolate for lunch - so considerably more carbs for the same amount of insulin! 😱 Evenings require even less insulin per carb, so I must build up sensitivity through the day and my liver settles down 🙄

I'm not Type 1, I'm Type 1-of-a-kind 🙂
 
I am so glad that you are finding you new way of testing interesting and helpful. Keep us posted how it continues 🙂
 
I have similar differences in insulin:carb ratio through the day, Alan - currently having 1 unit for about 7g carbs at breakfast and 1 unit for 21g carbs at lunchtime. I'd love to only have a 9.5 peak mid-morning though! Can't find a way to inject enough insulin to stop the peak without being hypo by lunchtime - the only thing that seems to work for me is fooling my body into not doing the liver dump by going back to bed straight after breakfast. It's weirdly counter-intuitive from the diabetes point of view, but if I don't go back to bed my bgl's likely to be 15 mid-morning and if I do it's likely to be 4.
 
So interesting! I am glad the numbers correlate between the two readings. I am going to buy one in May when I have more paid work happening, can't wait as I have had a nine month break.
 
It is amazing you achieve these flat lines without any basal! Must be reassuring to see and makes sense of your good HbA1c.
 
I do have to try a bit, honest! 😱 🙂

Actually, one year on my Diaversary I decided to have a 'day off diabetes' since I don't need basal. I didn't inject all day and tried to eat as low carb as I could all day. I seem to remember my numbers were in the 8s and 9s for much of the day. It would be interesting to try it again and follow what happens on the Libre.

It is actually 5 years ago this month that I stopped needing basal (I think, or is it only 4?). A GPSI told me that it would probably only last a week or two...🙄 Either my beta cells are made of stern stuff or my immune system is a bit of a wimp... 😉
 
Update: Well, I have been really pleased with the Libre so far 🙂 The biggest discrepancy between the scanner and a blood test has been about 1 mmol/l, which is well within tolerances, so I really can't complain about that and it means that I have been able to trust what it is telling me 🙂 I wouldn't say I'm doing fewer blood tests - maybe missing out one or two a day, but still doing my pre-meal and bedtime tests 🙂 It's given me a lot of information about how my blood sugar behaves and things I need to watch out for 🙂

One problem I had last night was a 'Sensor error' - told me to try again in 10 minutes, and it has been fine since - I presume others have had this on occasion? How often?
