I do 2 miles on my treadmill and it takes me about 30-31 min. I walk fast 3.8 to 4.0. I also run. Seems like I should be going farther than 2 miles. I am a sweaty mess when I'm done. I feel like I get in a good workout so I'm happy with it. I find the treadmill very boring.I watch tv and listen to music. During nice weather I like to walk outside 4-5 miles. There is no way I could stay on my treadmill that long.
