That is because I started like the flash that is why. And I am not the flash just to clarify. Actually I am so not the flash. Couldn't start slow. For some reason I overestimated how quickly I should have been going as per my plan. Yes I have to follow a plan in these early days otherwise will get lost easily. But follow it I should.
I am not feeling bad about it. I run after all. Just weird that my mind tells me to go slow and my body has no idea and wants to avoid (too fast or too slow) the target pace I so carefully set from my previous run. It has other plans.
