Don DeLillo keeps a steady, unspectacular schedule. He writes for about four hours in the morning, breaks for a run, then comes back for two or three more hours in the afternoon. The running isn't a hobby bolted onto the day. It's part of how he shifts gears.

The Direct Answer
About four hours of morning writing, a midday run, then two or three more hours.
DeLillo laid out this rhythm in his 1993 Paris Review interview, where he described the run as a way to move out of one mental world and into another.

The Shape of the Day

DeLillo starts in the morning at his manual typewriter and works for roughly four hours. He keeps the conditions plain. There's no snack food and no coffee at the desk, and no cigarettes either, since he gave up smoking long ago. The space around him is clear and the house is quiet. That quiet is the environment he says a writer fights to secure and then keeps finding ways to waste, staring out the window or thumbing through the dictionary for no reason. The morning block is where most of the real work happens, while his attention is freshest.

I work in the morning at a manual typewriter. I do about four hours and then go running.

The four hours aren't about volume. DeLillo works slowly and rewrites constantly, so the morning is less a race to rack up pages than a push to get a small number of sentences to sit right. He has never worked from an outline, so the day's shape comes from the sentences themselves rather than a plan he's chasing. When the session ends, he stops and moves.

Why the Run Matters

After the morning session he goes running. He's described the appeal in simple terms: the trees and birds, a bit of drizzle, a pause that lets him move out of one mental world and into another. When he comes back he writes again in the later afternoon for two or three hours, settling into the kind of absorbed book time where the hours pass without announcing themselves.

The run works as a hinge. It separates the two writing blocks and clears his head between them, so the afternoon isn't just a tired continuation of the morning. Plenty of writers use a midday walk the same way, though DeLillo is unusually direct about what it does for his attention. It fits a pattern you can trace across his day in the full Don DeLillo writing routine.
