Drink plenty of water but not too much
Breathe in through your nose and out your mouth
Stretch, especially your calf and tibialis anterior (front of your shin). That way you won't get crippling shin splints

Keep your breathing steady (I like to breath through my nose and mouth--doesn't really matter, since you'll get thirsty anyways...)

Drink plenty of fluids before (NO SODA!)

Don't eat a lot before running...

And most importantly, PACE YOURSELF (meaning don't start sprinting in the beginning and killing yourself in the end)
