The problem is, you need to prick your finger and take blood samples several times each month to calibrate sweat based glucose sensors, and even then it is not perfectly accurate. So you actually need to buy two devices to make this work based on the current technology. There's no way amateur Joe Schmoe cyclist is going to do this.Shrike wrote: ↑Mon May 31, 2021 12:10 pm
For now, for me anyway, it's one to watch and hope for. I hope they crack it and make is accessible through partners. If not, hopefully someone else comes along and pulls it off too - no reason why Garmin or Wahoo can't move into this game. Garmin are doing a billion in profit so they can certainly buy SuperSapiens or accelerate development, catch and overtake them - pushing them out of the market - if they think it's worth pursuing.
If you want "guesswork," you can just eat a gel every 45-60 minutes for every 2 hours you are riding. Or just stop and eat some cookies or pastries at the local cafe. For the perspective of a recreational cyclist, this is a much more enjoyable and "normal" routine than pricking your finger every week to tell you when you need to gel, and then strapping on another piece of equipment.
I am hopeful that in 2-3 years, we will have "one" sensor that will combine HR and lactic acid measurements. And if somehow the sensors can get good enough to accurately measure glucose levels without requiring calibrating finger pricks, that could be added as well.
