running outside > treadmill

Why it's better:

• It enables me to create bulleted lists, which I enjoy.
  
  
• Neighborhood kitties.
  
  
• Good people-watching, including Dude Pitching Golfballs on Sidewalk and Cute Mom Walking Viszla While Carrying Baby in Yellow Duck Jammies
  
  
• It's so easy to switch back and forth from fast to slow to match the tempo of my non-Apple mp3 player. Miley Cyrus's "Party in the USA": Speed up! Dulcet tones of Regina Spektor (phew, that's not as embarrassing): Slow down!
  
  
• Vitamin D. Thanks, sunshine! This encourages me to run farther, making me feel less guilty for eating whole blocks of cheese for dinner.
  

Why it's worse:

• Hills. That one on [street name omitted so as to foil internet stalkers' plans to creepily stalk] is excessive.
  
  
• Drinking fountains not as conveniently located.
  
  
• Sometimes, you see men peeing and/or wacking off in the alley near neighborhood pizza places. It's distracting enough to throw off one's pace, but hmmm, I guess it does inspire faster running.
