A couple of quick tips for running hills:
Look down and not at the incline angle on the horizon. Pull the brim of your hat down low to help.
Count backwards from 100 once the incline starts and just keep going. I have counted two sets of 100s doing this for a long hill before. Sometimes I've gotten delirious and skipped a number or forgotten what comes before 88. But it keeps me from thinking about The Hill.
Both of these tips were from the elite runner coach of our Team for Kids team while I was training for a previous New York City Marathon. I've followed them a long time and they work!
