By failing to prepare, you are preparing to fail.
You never know what motivates you.
Leap, and the net will appear.
The wise does at once what the fool does at last.
If you're going through hell, keep going.
I can, therefore I am.
Who seeks shall find.
Either you run the day or the day runs you.
Things do not happen. Things are made to happen.
Begin to be now what you will be hereafter.
I believe you'll develop speed via strength work which includes hill running, either repeats, or running hilly courses as the Kenyans do on a steady basis.
