What is Obstacle Course Racing?
OCR is a high-intensity, full-body sport that combines running with a series of strength, agility, and endurance-based challenges. From monkey bars and mud crawls to rope climbs and heavy carries, it tests physical and mental grit.
Events can range from 5km fun runs to long-distance endurance challenges. Some focus on speed and skill, others on teamwork and resilience. No matter the format, OCR demands training across multiple disciplines - and smart fuelling strategies to match.
Popular events across Australia include Spartan Race, Tough Mudder, True Grit, Raw Challenge, Obstacle Australia, and The Rugged Race.
What Supplements Are Good for OCR Athletes?
OCR athletes often use a combination of supplements to support training, recovery, and performance on race day. Below, we’ve broken down some common approaches by event type.
Obstacle Australia Supplements
Obstacle Australia events test functional strength and endurance across varied terrain and obstacles. With an emphasis on athleticism and grit, fuelling strategies often include:
- Intra-workout hydration with electrolytes
- Carbohydrate blends to support sustained energy
- Fast-digesting proteins for post-event recovery
Spartan Race Supplements
Spartan Races vary from 5km Sprints to 21km Beasts, with obstacles that demand explosive strength and long-lasting endurance.
- Beta-alanine is often used to support high-rep, high-intensity efforts
- Carbohydrate-based drinks may assist with fuelling during long events
- Electrolytes can support hydration and muscle function
The Rugged Race Supplements
The Rugged Race focuses on fun, community, and muddy, muscle-burning challenges over 6–8km courses.
- Lighter hydration and electrolyte support is common
- BCAAs or EAAs may be used for muscle support during the event
- Recovery blends are popular for post-race muscle repair
Tough Mudder Supplements
Tough Mudder emphasises teamwork and endurance over timed competition, but it’s still physically demanding.
- Electrolytes help support hydration over long courses
- Fast carbs may be consumed during longer events
- Protein blends are often used post-race for muscle recovery
True Grit Supplements
True Grit events are intense - typically 10km+ with military-inspired obstacles across rugged terrain.
- Beta-alanine is sometimes used to support muscular endurance
- Amino acids may help with muscle preservation in longer events
- Hydration support is key, especially in our warmer states
Raw Challenge Supplements
Raw Challenge is obstacle-heavy but often shorter in distance, making it a great entry point to OCR.
- Lighter intra-workout support such as electrolytes or BCAAs
- Short-burst energy sources like simple carb blends for repeat efforts
- Post-event protein to aid recovery and muscle repair
