Hoho, thought I was a little bit stupid before. I ran without changing speed
on the treadmill and when I felt tired I just suddenly slow down to walk.
Today I ran 4 miles at 6m/h and then another one mile at 5m/h. Felt totally
different.
I will try running slow and quick instead of walk and run during the process
.
