Confidence Power Plus Treadmill - I would take an outdoor run over a treadmill run on any day of the week. However, 30* is my cutoff for running outside, so on those (many, many, many) days of the year, this sweet machine is my BFF. It's teeny tiny, folds up for storage, and is priced reasonably. Be warned, though: it tops out at 6 mph. For a walker/jogger, no biggie. For a 7-minute-mile-marathoner, you need a faster treadmill, and you shouldn't be taking running advice from me.
Pepper spray - Because I am paranoid, and if you're running alone at nighttime, you should be, too. This one is small and cute and easy to pack in your fanny pack (see below!).
Brooks PureConnect 2s - My sneaks. I've sung their praises on here before, so I'll leave it at this: I love these shoes.
Lite pack - If you are dorky enough to run with a fanny pack (I am), this one is sleek and lightweight.
Old Navy compression legging - The bomb. I love them. They are so so long, and comfortable, and not see through, and warm enough for outdoor runs.
Headbands - Pretty much any wide, stretchy headband will do. I have some warmer ones I wear outside to protect my ears when it's cold, but when I'm inside, I just need something to hold my blasted bangs out of my sweaty face.
Map My Run - Website that lets you pull up your neighborhood and map your run, then lets you know distance, elevation, yadda yadda. It's awesome, especially if you're training for a race.
