Endurance Nutrition: Fueling Marathon and Long-Distance Performance

UNO Nutrition Team1 min read

Endurance athletes have unique nutritional demands that differ significantly from strength athletes.

Protein in Endurance Training

While carbohydrates fuel endurance exercise, protein plays crucial supporting roles:

Protein Functions for Endurance Athletes: - Repairs exercise-induced muscle damage - Supports immune function (heavy training suppresses immunity) - Provides alternative fuel during prolonged exercise (5-10% of energy) - Maintains lean mass during high training volumes

Recommended Intake: 1.2-1.4g protein per kg body weight

Timing Strategies

During Training Blocks:

  • Protein with every meal (20-30g)
  • Post-long-run recovery shake (25g protein + carbs)
  • Before bed: Slow-release casein (20g)

Race Day:

  • Minimal protein before/during race (focus on carbs)
  • Post-race: High protein for recovery (30-40g)

Carbohydrate-Protein Combinations

Research shows adding protein to carbohydrate recovery drinks may enhance glycogen resynthesis and reduce muscle damage.

Optimal Ratio: - 3:1 or 4:1 carbs:protein for endurance recovery - Example: 60g carbs + 15-20g protein post-long-run
