(NOT A SHITPOST) Does anybody have experience with putting thermometer in anus for heat training?
I am a rower (and do a ton of zwift-ing for overuse injury prevention) and am going to be racing in 95+ degree fahrenheit and humid conditions in about 4 weeks. I've been doing somewhat primitive heat training (layering up and just going off of feel @~45% ftp) but would like to actually measure my core temp so I can get to and stay in the 38.5-39.5 degree celsius range for getting peak adaptations.
$300 is a lot for the CORE strap, but this thermometer from Home Depot looks like it would fit fairly comfortably several inches up my posterior, and get a more accurate core temp (as it is literally inside my core, and unaffected by food + drink).
Do any of you have experience with putting this/a thermometer up there and how does it compare to other methods for tracking core temp during heat training?
