walked less than 3 miles and thought i was going to pass out

Hello

I went for a walk with a friend this afternoon.  We walked 2.7 miles; less than I had been able to do before the band but I got home and felt like I was going to pass out.  I sat down and sipped apple juice and pretty much have been relaxing all night now and still don't feel quite right.  Anybody know what happened?  I do live in AZ but it wasn't too hot today(mid-90s). 

thanks

Were you drinking at all during the walk? And how much did you have to drink prior?  Sounds like dehydration.  For temps in the 90s, the body will start to lose fluids very quickly even if you don't feel it.

I'm that mid-90s isn't hot!

I find I need to eat before I workout, if I want to have a good one. Maybe you just needed more fuel.
