You've heard the saying that the only thing constant is change, right?
Well, for me, when it comes to running, the only thing that's consistent is my inconsistent pace.
Today I had all the makings for a successful run: It was a beautiful, sunny day in the upper 40's and I was adequately rested, fed, and caffeinated. So, why did I run so much slower today than last time? Almost a minute/mile slower to be exact.
Sure, I know the "long" runs are about endurance, not speed, but at this stage in the game I don't exactly consider the runs I'm doing to be "long." (That starts next weekend.)
So, it remains a mystery to me what causes my pace to change so much from day to day; what causes me to run at such a good pace one day and then so slow the next.
Anyone else experience this or unraveled the mystery?
