Carb-loading: the point is “easy carbs,” not “stuffed”

Carb-loading works best when it’s practiced and paired with reduced training load.

48–72 hours out (simple structure)

  • Increase carbs gradually and keep meals familiar.

  • Reduce very high-fiber foods if they upset your gut.

  • Keep hydration normal; don’t force huge volumes.

The night before

  • Eat a familiar, carb-forward dinner.

  • Avoid “new” sauces/spice levels.

  • Prep breakfast and race-morning snacks.

Race morning reminder

Pair this with the race-day plan so breakfast and gels are predictable.

Training guardrails

  • Keep easy runs truly easy so workouts stay high quality.
  • Progress one variable at a time (volume first, then intensity).
  • Use cutback weeks every 3–4 weeks to absorb training.
  • If pain changes your gait, scale back and get assessed.
