I started jogging a bit the flat section of the loop, now I could do that in 3.5 minutes instead of 5.
I don't like shopping and shoe is probably the most difficult shopping item ever since I was a kid. I still have a few pairs of sport shoes which I seldom use may be they belong to the bin by now.
What I have been using is a just a cheap slip on which isn't meant for running. I'll need to shop for a pair of suitable shoes the coming weekend.
