Hi all, I've just completed wk4r2 and just wondered how fast people go? I use the treadmill and have not braved the outside yet so its sometimes difficult to know what to set my speed at. I do go very slow as so unfit and sometimes find myself lowering it to as slow as 6.0 which I have previously speed walked at! Does it matter what speed I do? I kind of feel like I am cheating by going so slow! Advice please!
