The following is clearly a bug, and it bugs me pretty much :)
Garmin-Kevin, I have been noticing for a while that the color of the Stamina remaining often get refreshed automatically.
It became obvious today during my marathon when as I was running for a while with the current screen being the stamina remaining distance gauge. then at some point I was feeling abnormaly fatigued and discoveres why when after changing to the next screen and coming back to the gauge it had changed from yellow to red!!!!!! Could have been coincidential but it's not the first time and during today's marathon only it did it 3 times!
It's clear to me there is an issue there.
