Haha loving this, I spent a lot of time on treadmills last year and it's so true. I used to spray the people either side of me.
It must be warm in gyms because they are aimed at people who aren't working very hard.
My thoughts on cooling was to ask for a big fan, but when I asked the manager suggested I run outside. A fair point. I'm only paying £100 a year tho. Other thought was to spray yourself with ethanol like Chris Boardman.
