Running outside vs. Treadmill?

Which do you prefer? Going for a run around the neighborhood or going to the gym and running on the treadmill?

 

Everyone has their different preferences. But me, I enjoy running outside way better than running on the treadmill. I get bored and probably don't run as much as I would if I was outside. I love the outdoors, my surroundings kept me motivated and I put length distances for myself to keep me going. For example, in the summer I would challenge myself to run to the local elementary school and back without stopping. I feel these options don't apply when you're just at the gym on the treadmill. Perhaps the best benefit or the treadmill is you can specifically time yourself, count your calories burning and change your elevation to your desire.
