The "something" that drives us

In every ultra, no one's race or finish is guaranteed. That goes for everyone - elite, non-elite, mid-pack and back-of-the-pack runners. So what happens for those that do manage to cross the line, come home safe and stand tiptoe above all the rest?

There comes a point during every race when ‘something’ kick-starts the lethargy out of you and drives your brain, heart, and body toward the finish-line.

I wholeheartedly agree,and can't say it any better. If get that "something," hold on to it and let it push you to wherever you want to go.
