Collection: LONG DISTANCE ENDURANCE FUEL | HAMMER NUTRITION UK

Long Distance Endurance Fuel for Ultra Events, Cycling and Triathlon

When your training or racing extends beyond two or three hours, your nutrition strategy becomes just as important as your fitness. The right long distance endurance fuel can mean the difference between maintaining a strong, consistent pace and watching your performance gradually decline as fatigue sets in.

For nearly 40 years, Hammer Nutrition has championed a different approach to endurance fuelling. Rather than relying on large quantities of simple sugars that can lead to energy spikes, stomach discomfort and inconsistent performance, our philosophy focuses on delivering steady, sustainable energy that supports both performance and long-term health.

At the centre of this approach is Perpetuem—Hammer Nutrition's flagship long-distance fuel, trusted by ultra runners, cyclists, triathletes and adventure athletes around the world.

Why Long Distance Athletes Need More Than Carbohydrates

As exercise duration increases, your body's nutritional demands change.

While carbohydrates remain your primary source of fuel, relying on carbohydrates alone during prolonged exercise can increase the risk of muscle breakdown, fluctuating energy levels and digestive discomfort.

Events lasting beyond approximately three hours require a more complete fuelling strategy that helps preserve lean muscle while continuing to supply steady energy.

This is where Perpetuem stands apart from traditional sports drinks and energy products.

Its carefully balanced formula combines complex carbohydrates, protein and healthy fats to provide sustained energy while helping to reduce muscle catabolism during long-duration exercise.

The result is a fuel designed specifically for endurance—not simply speed.

Perpetuem – The Ultimate Long Distance Fuel

Perpetuem has earned its reputation as one of the most respected endurance fuels available because it was designed specifically for athletes who spend hours on the road, trail or bike.

Each serving (1 scoop) delivers approximately 90 calories, including around 34g of complex carbohydrates, 5g of protein and a small amount of healthy fat.

The primary carbohydrate source is tapioca-derived maltodextrin, chosen because it provides efficient energy while remaining gentle on the digestive system.

Unlike many sports nutrition products that rely heavily on glucose, fructose or sucrose, Perpetuem provides smooth, sustained energy that helps minimise the highs and lows associated with high-sugar fuelling strategies.

The addition of protein plays an equally important role.

During prolonged endurance exercise, amino acids help reduce muscle breakdown and support recovery even before your session has finished. This becomes increasingly valuable during ultra-distance events, long sportive rides, Ironman® races and back-to-back training days.

Healthy fats provide an additional slow-burning energy source,reduce hunger making Perpetuem uniquely suited to events lasting several hours.

Together, these nutrients create one of the most complete endurance fuels available.

Ideal for Ultra Running, Cycling and Triathlon

Perpetuem is particularly well suited to athletes competing in:

• Ultra marathons
• Ironman® triathlons
• Long-distance cycling events
• Gravel racing
• Mountain biking
• Adventure racing
• Multi-day endurance events
• Long training rides and runs

Many experienced athletes begin their event using HEED for shorter efforts before transitioning to Perpetuem once exercise extends beyond three hours, helping maintain energy while protecting working muscles.

HEED – Perfect for Shorter Endurance Sessions

For endurance sessions lasting up to around three hours, HEED Sports Drink remains an outstanding choice.

HEED provides clean energy  110 calories per serving from complex carbohydrates together with a balanced electrolyte profile, making it ideal for marathons, shorter cycling events, tempo runs and everyday endurance training.

Because HEED contains no refined sugars, artificial colours or artificial sweeteners, it delivers consistent energy without the dramatic spikes and crashes often experienced with conventional sports drinks.

Many athletes also combine HEED with Hammer Gel during higher-intensity racing when additional calories are required.

Hammer Gel – Fast Energy When You Need It

There are times during racing when immediate energy becomes essential.

Hammer Gel delivers around 90 calories using Hammer's maltodextrin-based formula, providing quick, easily digestible fuel without excessive simple sugars.

Whether climbing a long mountain pass, pushing through the closing miles of a marathon or increasing pace during a triathlon, Hammer Gel offers a convenient source of rapid energy that integrates perfectly with a Perpetuem-based fuelling strategy.

Available in a range of natural flavours, Hammer Gel has become a favourite among endurance athletes seeking reliable race-day nutrition.

Hammer Bars – Real Food for All-Day Adventures

Not every athlete wants to consume liquid nutrition throughout an entire event.

For cyclists, ultra runners and adventure athletes spending many hours outdoors, Hammer Bars provide a welcome whole-food alternative giving between 240 - 260 calories per bar(flavour dependent)

Made using quality ingredients and free from unnecessary additives, Hammer Bars offer satisfying nutrition that complements liquid fuels such as Perpetuem.

Many athletes alternate between Perpetuem and a Hammer Bar during particularly long events, helping maintain both energy intake and appetite over many hours.

Complete Your Fuelling Strategy with Electrolytes

Energy alone isn't enough.

Sweat losses during prolonged exercise remove important electrolytes that help regulate muscle contraction, hydration and nerve function.

Hammer Nutrition's Endurolytes® range replaces these essential minerals without relying on excessive sodium alone, allowing athletes to tailor electrolyte intake according to weather conditions, sweat rate and training intensity.

Using Perpetuem alongside Endurolytes creates a comprehensive fuelling strategy capable of supporting endurance performance in a wide variety of conditions.

Fuel Smarter for Longer

Successful endurance athletes understand that nutrition is more than simply consuming calories.

It's about providing the body with the right nutrients, in the right amounts, at the right time.

Hammer Nutrition's long-distance fuelling philosophy has helped athletes around the world complete marathons, ultra races, Iron. distance triathlons and epic cycling adventures with greater consistency and fewer nutritional problems.

Whether you're preparing for your first century ride or your next ultra-distance event, Perpetuem provides the sustained energy, muscle support and nutritional balance needed to perform over the long haul.

Combined with HEED, Hammer Gel, Hammer Bars and Endurolytes®, it forms a complete endurance nutrition system that has been trusted by athletes for nearly four decades.

When the hours add up and every kilometre matters, choose long distance endurance fuel that's designed to go the distance.
