Update from windy Scheveningen: Yesterday I did 16km and today 20km at slow pace. I am feeling pretty tired, I suspect it's due to the very long days: I tend to spend more time outside and sleep less. As a consequence, yesterday I didn't go to work, I stayed home and slept 6hrs!
I am planning to pick up the pace on Fri or Sun, depending on the wind (seriously, 5bft do not let you do any temp/speedwork at all!). If I am still tired by the end of the weekend, then I will follow a mini-regeneration programme I have in mind for next week. We'll see!
