running

Long runs are where the hard problems come loose. The first hour belongs to the body; after that the mind is free to turn over whatever the desk could not resolve. Debugging works the same way: force rarely helps, distance does, and what surfaces is usually not the fix but the wrong assumption underneath it.

The cockpit teaches the stricter version. Fly the aeroplane first, and the right problem shows itself in the time that buys. Running offers the same time without the altitude, by removing every option except patience. Which here is not a virtue but a technique, and the one that separates a patch that works from an answer that is right.

I had run marathons before. Many of them. Edinburgh, Hamburg, Valencia, Porto, Budapest — cities I wanted to see on foot. At some point a marathon on a Saturday became a training run. And then, inevitably, further. Ringkøbing became my first real ultra: one hundred kilometres around the Ringkøbing Fjord in Denmark, clockwise.

I knew I would break. At seventy kilometres I thought I was dying. At eighty I have almost no memory. At ninety I stopped thinking entirely. My daughter ran the last ten kilometres beside me. I finished. For days afterwards I walked like an old man — and made plans for the next one.
