There is a phenomena in running that my husband & I have dubbed the "second sweats".
Second sweats happens after you have already run and have already showered. You're nice and clean, smelling fresh like a daisy and then BAM! You're sweating. Your internal core temperature is rising with every passing second. That clean shirt you just put on? Soaked. Ladies, let's not even talk about your bra and underwear.
Enter the house coat.
