Run the Mile You're In: Halfway Points, Intentions, and Presence

I have fallen into a questionably healthy habit (according to my hamstring, at least) of running for very long stretches at a time. Four, six, and eight hour runs have become fairly standard in my training cycles; I crave the opportunity to push myself, mentally and physically, to do more, just as I crave the exhaustion they bring. This habit has taught me many things, but of those things, this one stands out: Run the mile you're in. 

Halfway through a 50k is (approximately) 16 miles.

Here's the thing about 16 miles: it's a lot of miles, no matter how you look at it.

Spend too long thinking about how far you've already gone, and your mind and body become exhausted with recognition of what you've done. I've already run sixteen miles. Am I not done yet?

Spend too long thinking about how far is yet to go, and your mind and body become exhausted with the sheer weight of what's to come. I have sixteen miles left. I'll never get there.

It's a lesson I've found invaluable in life as well as running: presence is about more than attention. It's about recognizing where I am in a process, where we are in a process, acknowledging how far we've come and how far is left to go, knowing how to get to a finish line, whatever that may look like, all while holding on to what is immediate.
