did a solo ride on a hot day years ago - high temp in the 90's so my riding buds opted out
did not feel good as ride progressed - and at that time heat usually did not affect me that much
around half way or so through the ride after a slight climb began to feel worse and took a break in the shade near a farm
was sitting against a fence and sloshed my water bottle around - and soap suds appeared
I was drinking soapy water
ugghh
