This morning I completed my last run before the Philadelphia Half Marathon this Sunday. Just like when I was training for both marathons, I did most of my training for this race on the treadmill. I know there are some runners out there who would never be caught dead on a treadmill and will tell you why running on a treadmill isn't really running, but it works for me. Especially this time of year, daylight hours are limited, and sometimes 5:00am is the only time I can get in a solid run. I love doing intervals and speed work on the treadmill, and I truly believe that treadmill running has contributed to my ability to run at an even pace.
Call me crazy (you wouldn't be the first one), but even though I can set a cheap treadmill and a super nice gym-quality treadmill to the same speed, running always feel more pleasant and "easier" on the nicer treadmill. The better quality treadmill is smoother and it just feels like I don't have to put in as much effort to hit the same speed.

Ability to watch TV
Although I typically run with music while running outside, I can also run with no music or while talking to a friend. When I'm inside on a treadmill, the ability to watch TV can make or break my run. It doesn't need to be something super interesting (at 5:00am, it's a recap of last night's shootings/robberies, the weather and the traffic, or that time when a women was rescued from in between bleachers at Wilmington University), but it's just something to take my focus away from running.
