What should I eat the night before a half marathon to optimize my performance and ensure I have sufficient energy for the race? Is it crucial to focus on carbohydrate-rich foods, or should I also incorporate proteins and healthy fats into my dinner? How do macronutrient ratios play a role in my overall energy levels during the run? Are there specific foods that experts recommend for such a pre-race meal, perhaps something easily digestible yet nourishing enough to sustain me? Furthermore, how should I consider hydration levels as part of my evening routine? Could the timing of my meal impact my performance come race day, especially if I’m prone to digestive issues? Might indulgent options like pasta or rice be beneficial, or should I lean towards lean proteins and vegetables for a balanced dinner? Is there a critical window of time after eating that I should be aware of to maximize my readiness for the challenge ahead?
