My treadmill finally arrived yesterday (the second one I ordered as the first one got lost in the warehouse). So after not running since over a week ago I set up the treadmill and got started on a warm up walk then increased the speed. I thought I was running about the same speed as outside but obviously not as I only did just over 2.5 k in 30 minutes! Horrendous! So, tonight I increased the speed and got a bit better. It's so different to running outside, my legs ached today at work and they feel like marshmallow when I get off the treadmill. No dizziness though as some people have said they get. I'll get the speed right when I get used to it and must remember to turn the heating off first...I was a tad warm lol!
