Lol thankyou guys--I just got back from riding finesse whew lol I forgot to put sunblock on and now im burnt :( lol i'm only putting an hour on each horse but making sure they have plenty of water!
Sorry to hear you got burnt. I'm not worried about the horses being out an hour, but worried about you. Heat stress could be bad and an unexpected dizzy spell while on horseback could be bad. Take care of yourself and make sure you are cooling down between rides. Cool water on your wrists and face will help.
The main reason why I live in Canada. It's never "hot" for very long and we have fantastic spring and summer months before we are hit hard with snow again :)
