I've run 15 marathons — here are the fueling dos and don'ts I've learned along the way

AI Briefing

• – Don't rely solely on the fueling plan from your training; instead, test it 2-3 weeks before the marathon.
• – Eat a light meal or snack about 1-2 hours before the start, and avoid heavy, greasy foods that can cause stomach upset.
• – Hydrate adequately the night before and during the race by drinking water or sports drinks, but avoid drinking too much water in the final 30 minutes before starting.
