Incline

So I have been reading a lot about incline on the treadmill. So far I have been running at a 0 incline, when I am on the treadmill. From my reading you should increase the incline somewhere between 1 and 2 to make it more realistic to outside conditions. Considering you will pretty much never have a race on a treadmill I feel I need to simulate outdoors as much as possible. So I have settle to increasing my incline.
I do try to get outside as much as possible but lately our temperature has been bitter cold. But I have gone out a few times.

In the end... no more "0" incline. Race season is coming faster than we all think... time to get ready!
