How to track food during marathon training without burning out

A system you can keep for 16 weeks, not 16 days. · 2 min read · Updated September 30, 2026

In short: Food tracking often gets dropped because it’s a chore. A lighter system for a whole training block: log in the moment, track what matters for training, review weekly, and skip what doesn’t help.

How we made this guide: this is practical advice for keeping a training log going through a block. For research-based numbers, see carb loading and protein.

Plenty of people who start tracking food drop it after a few weeks. Usually the reason is practical: typing every ingredient into an app is tedious, and training blocks are long. Here’s a lighter system built for a whole block.

1. Log in the moment, not at night

Reconstructing a day from memory is where tracking falls apart. Log each meal right after you eat it, even roughly.

2. “Roughly right” beats “perfect and abandoned”

You don’t need gram-level precision to see patterns. “Rice, salmon and broccoli, a normal plate” is enough to tell a long-run day from a rest day.

3. Track what changes your running

Carbs around long runs and hard sessions, protein across the day, and how each run felt. That’s most of the value; you can skip the rest.

4. Review once a week

Ten minutes on Sunday: which runs felt good, what you ate before them, and whether your eating moved with your training. Then adjust one thing.

5. Remove the typing

This is the part we built My Track Record for: you tap, say what you ate or what you ran in one sentence, and it’s logged with calories and macros. The fewer steps logging takes, the longer you keep doing it.
