I did another 6.5k on my treadmill as it's so cold and my hands and feet are hurting but it was so hard. After 10 mins I was puffed and legs were heavy but I did keep going for 45 mins and get to my 6:5k. Immediately afterward I felt good as we all know we do and that's the feeling we crave. How ever 3 hrs later my legs have not recovered and I would go as far to say they are hurting especially at the top of each calf. I did notice the treadmill kept changing the incline between 1 and 3% randomly well probably not randomly I expect I randomly hit a button I should not have! I missing the outdoor runs but throughly enjoy reading all your antics so keep it up people!
