I sweat a lot when I exercise. After an hour of running at medium intensity (~150bpm avg HR) in 20°C @ 50% humidity, I am literally drenched in sweat. I can wring my clothes and sweat will pour from it. It’s difficult to find clothes that are comfortable to wear for my long trips.
I don’t really feel comfortable changing shorts and underwear on the side of the road, which is the biggest issue WRT sweating for me. I’m running on the country side, lots of cars and open space and nowhere to “hide” while changing.
Fair, the other stuff should help though, especially cloths that dry fast. Anything cotton is just going to act like a sponge.
