A simple, step-by-step fueling strategy for first-time half marathoners, including breakfast timing, gel count, and hydration targets.

RunningHalf MarathonRace Day

Quick Answer

A beginner half marathon fueling plan should include a familiar carb-focused breakfast 2-3 hours before the start, 30-45g carbs/hour during the race, water or electrolytes based on conditions, and no new foods on race day.

Most first-time half marathoners need 1-3 gels depending on finish time and carb tolerance.
Practicing breakfast and gels in training reduces GI risk on race morning.
MAVR personalizes gel count, carb targets, and hydration by finish-time goal and weather.

Your Beginner Fueling Numbers

  • Breakfast: 1–2g carbs/kg, 2–3 hours before start.
  • During race: 30–45g carbs/hour.
  • Hydration: drink to thirst, usually 400–700ml/hour depending on weather.
  • Sodium: 300–700mg/hour if you sweat heavily or race in heat.
