For over 39 years, Hammer Nutrition has helped endurance athletes fuel smarter through scientifically developed products designed to support sustained energy, hydration, and recovery. Unlike many conventional sports nutrition products that rely heavily on simple sugars, Hammer's approach focuses on steady energy delivery, digestive comfort, and long-term endurance performance.

Running places unique demands on the body. Every step creates impact forces that increase muscle breakdown, fluid losses, and energy requirements. Whether you're running for fitness, racing competitively, or training for an ultra-marathon, understanding how to fuel properly can help you avoid fatigue, reduce recovery time, and enjoy more consistent performance.

The Three Foundations of Running Nutrition

Successful running nutrition revolves around three key areas:

Fuel

Your body relies on stored glycogen and fat to provide energy during exercise. As training duration increases, maintaining a steady supply of calories becomes increasingly important.

Many runners experience energy crashes late in races because they wait too long to fuel or rely on products that cause blood sugar spikes followed by sudden drops in energy.

Hammer Nutrition offers several fueling options to support runners at every distance:

• Hammer Gel provides concentrated, easy-to-carry energy ideal for training and racing.
• HEED Sports Drink delivers a balanced source of calories and electrolytes for shorter to medium-duration runs.
• Perpetuem is designed for longer endurance efforts where sustained energy becomes critical.
• Perpetuem Solids provide a chewable option for runners who prefer solid fuel during long events.

The goal is not to consume as many calories as possible but rather to provide your body with the steady energy it needs while maintaining digestive comfort.

Hydration

Even mild dehydration can affect pace, concentration, endurance, and recovery.

Every runner loses fluid through sweat, and those losses increase significantly during hot weather, long runs, and races. Replacing fluids alone may not be enough, as sweat also contains valuable electrolytes that play an essential role in muscle function and hydration.

Hammer Nutrition's hydration range helps support electrolyte replacement during training and racing:

• Endurolytes provide broad-spectrum electrolyte support.
• Endurolytes Extreme offers additional sodium for heavy sweaters and hot-weather running.
• Endurolytes Fizz provides convenient everyday hydration support.
• HEED combines calories, hydration, and electrolytes in one solution.

Proper hydration planning becomes increasingly important for marathon runners, ultra-runners, trail runners, and athletes training in warm conditions.

Recovery

Training adaptations happen during recovery, not during exercise.

Without proper recovery nutrition, runners may experience increased soreness, prolonged fatigue, and reduced training quality. Supporting recovery helps replenish glycogen stores, repair muscle tissue, and prepare the body for future sessions.

Hammer Nutrition recovery products include:

• Recoverite for post-run carbohydrate and protein replenishment.
• Plant Protein for high-quality plant-based recovery support.
• Vegan Protein Bars for convenient recovery and meal replacement nutrition.

The faster you recover, the more consistently you can train.

Running Nutrition by Distance

Different race distances require different fueling strategies.

5K & 10K Running

For shorter events, many runners can perform well using a pre-race meal, good hydration, and optional use of Hammer Gel before (15 mins prior ) or during harder efforts.

The primary focus should be on arriving at the start line properly fueled and hydrated.

• Hammer Gel during the race or 15 mins prior 
• Heed - Regular hydration 1 hour prior and during

Half Marathon Nutrition

As race duration increases, fueling becomes more important.

Many runners benefit from:

• Hammer Gel during the race or 15 mins prior 
• Heed - Regular hydration 1 hour prior and during
• Endurolytes capsules -Electrolyte replacement in warm conditions taking 1-2 hourly 

Practising your race-day nutrition strategy during training is essential.

Marathon Nutrition

Marathon success often depends as much on fueling as fitness.

Many runners experience a dramatic drop in pace late in the race due to poor energy management. A consistent nutrition strategy that includes calories, fluids, and electrolytes can help maintain performance over the full distance.

• Hammer Gel during the race or 15 mins prior 
• Heed - Regular hydration 1 hour prior and during (option)
• Endurolytes capsules -Electrolyte replacement in warm conditions taking 1-2 hourly 
• Perpetuem Solids - 1 -2 taken hourly (Chew with water) this gives the added protein component
• Anti fatigue Caps - Ammonia scavenger helps prevent heavy legs syndrome.
• Endurance Amino - BCAA's helps slow down muscle

Ultra Running Nutrition

Ultra-distance events present unique nutritional challenges.

Hours of continuous exercise place significant demands on energy systems, hydration, and digestion. Ultra-runners often combine :-

• Hammer Gel during the race or 15 mins prior 
• Heed - Regular hydration 1 hour prior and during (option)
• Endurolytes capsules -Electrolyte replacement in warm conditions taking 1-2 hourly 
• Perpetuem Solids - 1 -2 taken hourly (Chew with water) this gives the added protein component
• Anti fatigue Caps - Ammonia scavenger helps prevent heavy legs syndrome.
• Endurance Amino - BCAA's helps slow down muscle 

  cannibalism.

Hydration & Electrolytes for Runners

Many runners only think about hydration when temperatures rise, but electrolyte replacement is important year-round.

Electrolytes help support:

• Fluid balance
• Muscle function
• Nerve transmission
• Endurance performance

Heavy sweaters and athletes training in hot weather often require additional sodium support, making products such as Endurolytes Extreme particularly useful during demanding conditions.

Maintaining electrolyte balance can help support consistent performance during long training sessions and races.
