Running day. Still doing week 2, so it was the second go at that level.

I tried to put some variation into the runs today, speedwise. There were six running bits in all, and I tried to do every second one at a slowish pace and every other one faster.

This lead to a surprising discovery! Slower is not actually easier at all.

The slow runs were easy on the lungs and breathing, but they all quickly gave me lead-legs, especially in the calf area, but also to some degree shins.

The faster runs required a lot more work from the lungs and for me to pay attention to breathing rhythm, but my legs felt fine.

I have never noticed this before. I expect it has something to do with the slower runs having shorter and therefore more steps, so the leg muscles work harder.

I found it quite interesting, so I shall be playing some more with speed variation, I think.
