Struggling... 16km easy

This morning I felt like I do the morning after a hard race! The only difference is that I have had an easy week of relatively little mileage, and no intensity whatsoever. The planned ParkRun went out the window (I woke up not wanting to do it, but once I started running, I knew that I had made the right choice). Thought something is better than nothing, so just ran the usual Lagoon, Shelly, Fairlight loop and return. Didn't look at my watch once (4:21's it was in the end). I will try and join the crew for the long run tomorrow, and then off for a blood test early next week just to make sure everything is ok. A nice morning to run with a cooler southerly wind blowing keeping the heat and people away.
