Carbohydrates are the body’s preferred fuel for high-intensity exercise, and OCR is no exception. Understanding the different types of carbs, when to eat them, and how they support performance can help you tackle every obstacle with more energy and recover faster.

Types of carbohydrates

Carbs come in different forms, each serving a unique purpose:

  • Simple carbs: Quickly digested sugars found in fruits, honey, or sports gels. Perfect for a fast energy boost during or right before a workout.
  • Complex carbs: Starchy foods like oats, brown rice, potatoes, and whole grains. They release energy slowly, keeping you fuelled for longer periods.

Fiber is also a form of carbohydrate found in vegetables, legumes, and whole grains. It’s essential for digestion, but slower to convert to usable energy, so it’s best eaten well before training rather than immediately pre-race.

Fueling for OCR

OCR combines bursts of strength with periods of running and endurance. Your body benefits from a mix of carb types to keep energy steady throughout:

  • Before training or racing: Focus on complex carbs to top up glycogen stores. Examples include oatmeal, whole-grain toast, or sweet potatoes eaten 2–3 hours before exercise.
  • During longer sessions or races: Simple carbs help maintain performance and prevent fatigue. Sports drinks, energy gels, or fruit like bananas work well.
  • After exercise: Carbs are crucial for recovery. Pair them with protein to replenish glycogen and repair muscles. Examples include rice with chicken, sweet potato with beans, or a smoothie with oats and yogurt.

Choosing carb sources wisely

Opt for foods that provide both energy and nutrients. Fruits and vegetables offer natural sugars, vitamins, and antioxidants, while grains and legumes provide sustained energy for endurance. Energy bars or gels can fill gaps when you need a quick boost on the course.

Timing and portion matters

Eating too close to training can cause discomfort, so aim to consume a pre-workout meal 2–3 hours in advance. During races or long sessions, target 30–60 grams of carbs per hour. After training, eating carbs within 30–60 minutes helps maximise glycogen replenishment and aids recovery.

The key takeaway

Carbs are essential for OCR performance. Complex carbs support endurance, simple carbs give bursts of energy, and timing intake around training and recovery ensures you have the fuel to tackle obstacles, complete the course, and bounce back faster.
