What to eat the night before a long run

A normal dinner done well beats a giant one. · 2 min read · Updated September 30, 2026

In short: The night before a long run, eat a familiar, carb-based dinner at a normal size. Daily carbs matter more than one meal; a full carb load is only for races over about 90 minutes.

How we made this guide: we built it from the research below and checked every number against it: ACSM, Academy of Nutrition and Dietetics & Dietitians of Canada joint position stand (2016).

The dinner before a long run gets a lot of attention, but your muscles fill their carb stores over the whole day, so the dinner is one part of it.

What matters more than the dinner

Your carbs across the day before. If you train 1–3 hours a day, the ACSM joint position stand (Thomas, Erdman & Burke, 2016) puts daily carbs at 6–10 g per kg. For a 150 lb runner that’s about 410–680 g across all meals, not on one plate.

The dinner itself

Carb-based: rice, pasta, potatoes or bread as the base of the plate.
Familiar: something you’ve eaten before a long run without problems.
Normal size: a bigger-than-usual plate can sit heavily the next morning.
Lighter on fiber and fat: many runners find it easier on the stomach.

Examples

Pasta with tomato sauce and chicken
A rice bowl with salmon and vegetables
Potatoes, eggs and toast

When it becomes a carb load

Only before races over about 90 minutes, and then for 36–48 hours, not one night. See the carb-loading guide.

Keep the dinners that work

Note what you ate the night before each long run and how the run went. After a few weeks you’ll have a short list of dinners you trust. We built My Track Record so logging that dinner is one spoken sentence.
