Interesting observations! I fitted Garmin Rally Keo power pedals to my 2 road bikes. With the xDrip data field for my glucose from my Abbot Libre 3 I get all data into a neat diagram in Garmin Connect. So your problem can be solved! It is just that power pedals are rather expensive...

Garmin produces loads of data! Like most triathletes I like to look at my training data, but I have begun to be a little more relaxed about them. The main issue is to avoid overtraining. I try to listen to my body as much as I can. My idea is to use objective data to calibrate my listening...

The is also the Sapiens. That's a Libre 2 sold to non-diabetic athletes under a different subscription model and using different software. Kristian Blummenfelt wears one.

Very interesting read! Since you use xDrip: Garmin iQ connect has an xDrip data field for BG. When you have a Garmin watch with a colour display (e.g. Forerunner 945 and above) you can have a watch face showing your glucose even if you don't exercise (not supported on an Instinct 2). When you...

Allan Hovda (one of Norway's leading triathletes doing Ironman) told us on a training weekend that he eats food packages labeled with gram carbohydrates 60 g per hour or more. He tops this up with water from the food stations. He estimates his water loss given temperature and race profile and...

Interesting new angle for interpreting my data! My first comment is that we do different types of exercise. In my 20 s I spent my holidays cycle touring the more remote parts of Britain. A typical day tour could be 130 km and I would spend 8 h in the saddle. (I have 2 custom frames: An Argos of...

Joe Friel has written an excellent chapter (#3) on nutrition during exercise in "Your first triathlon" (available via Amazon Kindle). Of course all this needs to be modified for us diabetics. The important thing is that the ability of the gut to absorb carbohydrates under exercise is limited and...

Thanks a lot for the link, I will investigate. I am in the lucky position that there are close ties between Bergen and Denmark including direct flights to Copenhagen. Novo Nordisk is a diabetic-friendly company. (Abbott is in my experience the opposite. They are not at all interested in patient...

My rule of thumb is that I use 50 % of my regular insulin when I exercise. This has changed over the years. Initially, I used no insulin at all.

The answer is that my carbo hydrate loading has evolved over time. I was an active cyclist since my late teens. However, after I got DM in 2004, anything more than 20 min exercise would give me hypos until I was shaking and my vision was impaired. I tried a cycle tour of some 30 km on a sunny...

Dear Simon, Our discussion is getting really interesting. I will split my answers into separate posts. I apologize for being imprecise: I referred to the weight of the muesli mix in grams. The label claims 61 g CH per 100 g, so 120 g = 73 g carbohydrates. With milk and yoghurt surely 80 g.

I promised more information regarding my system of carbohydrate loading. I apologize that the next paragraphs are very detailed, but if they weren't, the information would be useless. I use MDI with Novorapid at meals and Tresiba 10 IU at night. Since I swim s lot and have very sensitive skin I...

Dear Simon, Thanks a lot for considering my posts so seriously. On Sunday, I performed my first Olympic triathlon. That's what I was training for, but I did not write this as yet, thinking it would have been bad karma. To be honest, the thought of having to swim 1.5 km in open water gave me...

I put my Abbot Libre sensors (1, 2 and since this year 3, which is smaller) on the back of my arms, a little to the side so that my arm doesn't rest on the sensor at night. I am training for triathlon with daily exercise and swimming 3 times a week. Unless I swim on my back and my sensor arm...

(Mod edit) Thanks a lot! I am looking forward to your post. I am glad I found a forum of like-minded people. To be honest, I hate my diabetes and don't want it to limit what I do, but diabetes is stronger than me if I am not smart. And: I am in a much better shape and feel that I have a richer...

Thanks a lot! Lactate testing is the established way how professional endurance athletes find out what level of exercise intensity they can sustain over approx. 30 min. You can use this information to guide your training. 80 % of training of an endurance athlete is supposed to be under that...

Dear Simon, Excellent! I did not expect that anybody would be interested. I found zero information on lactate testing in diabetics on the net, so somebody has to get the ball rolling. The important thing about exercising for me: It keeps the boredom out of my life! I bought my first lactate...

I went all in for triathlon since March 2022. I am 59 and have DM1 since 2004. Since March 2023 I took up lactate threshold testing, both for running and cycling. I need to load carbohydrates before exercising - usually 120 g muesli and 8 IU insulin (some 60 % of the dose with the same meal and...

I am 59 and have DM1 since 2004. The way I respond to insulin and meals and endurance exercise has changed during the years. It trial and error, and you are aiming at moving targets... The real game changer has been continuous glucose monitoring on my Garmin watch. I found a hack based on xDrip...

I am 59, 183 cm with DM1 since 2004. I was 100 kg until 2 years ago when I developed insulin resistance on top of my DM1. I was prescribed Forxiga (daplaglifloxin) 5 mg, which helped me to lose excessive glucose via my urine, but which has been taken from the market for DM1 because of deaths due...
