Amateur cyclists already wear CGMs, and as a type 1 myself, they see mine and start asking all about CGMs. It must be so boring for them to worry about fluctuations between 85 and 120.

I don’t think amateur cyclists will have much to gain from this other than satisfying their curiosity.

Before buying one, just know that fit cyclists will appear glucose intolerant on a CGM. See Fig. 1 at https://pmc.ncbi.nlm.nih.gov/articles/PMC10933193/
