Today I have run about 7 miles and walked additional one. Bryn Mawr - Belmont Harbour and back. The heart, lungs, joints and muscles did not complain at all.
I decided not to starve the body. After the last run I decided to carry a Powerbar with me and eat it at the mid-point.
The sun and the heat really got to me. Even with plenty of water drank, I started to have cold-chills which are a sign of the heat exhaustion. I had the headache until the late evening. After the run I spent some time sitting in the lake's shallow water enjoying the cool water and a nice sunny day. Got some sun-tan, too.
