Yes, as much as you try, as much as you prepare, there are days you just don't have it.
Tonight was one of those nights. Hill work scheduled with the Pacers.
Half way up the first one, coming around the corner,
tried to shift into the next gear, and there was nothing there.
The legs never got going. There was no "second wind".
There was nothing in the tank.
So you make the best of it. You go through the motions.
You concentrate on your form. On doing what you can.
And then it will be over for that day. You can rest, recover
and enjoy the next day when it will be better.
