Physiological Requirements for Completing a 100K Ultra

Basic Completion Requirements

Nutrition Strategy for 100K

Calorie Calculation:

• A 100K typically takes 12-20 hours to complete
• Approximately 500-800 kcal burned per hour (depending on pace and terrain)
• Total calories needed for the entire race: 6,000-15,000 kcal
• Realistic intake: Usually 200-350 kcal per hour

Nutrition Principles:

1. Consume food or drink every 20-30 minutes
2. Do not wait until you are hungry to refuel (it is already too late)
3. Replenish fluids and electrolytes together (not just water)
4. Solid food may become difficult to swallow in the latter half; have liquid nutrition on hand
