Carb Loading for Running

Carb loading for running increases carbohydrate intake before long races to maximize glycogen stores. It matters most for half-marathon and marathon distances when paired with taper.

Carb loading for running tops muscle glycogen before long races by raising carbohydrate intake two to three days out while tapering training. Modern protocols favor moderate surplus over extreme stuffing that upsets gut.

Short races need less loading than marathons.

Common questions

  • Do all runners need pasta parties before races?

    Short events need less loading; marathons benefit from topping glycogen without extreme bloat. Increase carbs two to three days out while keeping familiar foods unless your gut tolerates change.
