For me, I like to run "against" the wind when first starting out. Running directly against the head wind - if possible. When I reached my limit of "fighting against the wind", I then turn around, and comfortably cruise back home. And when I get home, my body has decompressed. If I jog "with the wind" and turn around to jog back "against the wind", my body is already tired. Fighting back "against the wind" would over stress my cardio system. And if over stressed too much, could cause a heart attack. For me, hard battle at the beginning of my run and "cruise down" during the last half of my run works best.
Hope this helps...
