Half Marathon Training Nutrition Plan: Fuel Workouts, Long Runs, and Race Week

A practical half-marathon training nutrition plan for runners who want workout-specific fueling instead of a generic calorie target.

A half-marathon training nutrition plan should change by workout type. Easy runs usually need normal meals, quality workouts need carbohydrate before and after, long runs should practice race fueling, and race week should reduce surprises while keeping glycogen high. MAVR is built for this because it connects nutrition targets to the actual runs on your calendar instead of giving every day the same calorie goal.
