Just yesterday I wrote how good my legs felt and that I'm burning rubber. Last night coming home around 7pm. it was late and cold but I wanted to do an easy run. I thought a short warm-up and little stretching would be sufficient but after 2K my calf started to ache. I tried to run to the 3K turning point but at 2.5K I turned back home with an easy jog. I jumped into the shower to run cold winter water over my lower leg. It felt good (physically) but mentally very disappointing to have to refrain from running for a couple of days again.
