Feeding the Performance Horse: Recovery After Competition
Training and competition place significant physical demands on your horse. Whether competing in dressage, eventing, endurance, racing, show jumping or any other discipline, what you feed after exercise can have a major impact on recovery, future performance and long-term health.
Recovery nutrition is particularly important for horses competing over consecutive days or undertaking prolonged, high-intensity exercise, where replacing lost nutrients quickly can influence both recovery and subsequent performance.
Following intense exercise, there are three key nutritional priorities:
- Rehydration
- Replenishing muscle glycogen (energy stores)
- Muscle repair and recovery
Rehydration Comes First
Sweating is the horse’s primary method of cooling itself during exercise.
Along with water, sweat contains large amounts of electrolytes including:
- Sodium
- Chloride
- Potassium
- Small amounts of magnesium and calcium
These electrolytes are essential for normal nerve function, muscle contraction and maintaining fluid balance throughout the body.
If these losses are not replaced, dehydration can lead to:
- Reduced performance
- Muscle fatigue
- Delayed recovery
- Increased risk of colic
- Electrolyte imbalances
When Should Water Be Offered?
Once your horse has cooled down and breathing has returned towards normal, fresh, clean water should be offered.
Modern research has shown there is no benefit to withholding water from a horse that has been appropriately cooled following exercise. Allowing horses to drink when they are ready helps restore hydration more quickly.
Why Electrolytes Matter
Sodium plays a critical role in stimulating thirst.
Replacing sodium, together with chloride and potassium, encourages horses to drink more water, helping restore normal hydration status after exercise.
Electrolyte replacement should always be accompanied by unrestricted access to fresh drinking water.
Replacing Energy Stores
During moderate to high-intensity exercise, horses rely heavily on muscle glycogen.
Glycogen is simply the storage form of glucose within muscles and the liver and acts as an important fuel source during exercise.
Think of glycogen as your horse’s fuel tank.
Once those stores become depleted, fatigue develops and performance declines.
This becomes especially important during:
- Multi-day competitions
- Endurance rides
- Back-to-back training sessions
- Horses undertaking repeated high-intensity exercise
Replacing glycogen stores promptly allows the horse to recover more efficiently before the next workload.
Feeding After Exercise
Forage
High-quality forage should be offered as soon as the horse has cooled down and is comfortable eating.
Forage provides:
- Fibre for hindgut microbes
- Digestive stability
- Saliva to buffer stomach acid
- Additional water intake
Maintaining fibre intake after exercise also helps support hindgut health during periods of physical stress.
Grain
For horses performing prolonged or intense exercise, concentrates containing cooked, extruded or micronised grains can assist with glycogen replenishment.
The starch within processed grains is digested in the small intestine and absorbed as glucose, allowing muscles to rebuild glycogen stores more rapidly.
Ideally, concentrate feeds should be offered within one hour after intense exercise, once the horse has cooled, rehydrated and is settled.
For endurance horses continuing to compete during an event, grain meals should remain small—generally no more than approximately 200 g of concentrate per 100 kg body weight between veterinary checks—to avoid large insulin responses or digestive upset.
Supporting Muscle Recovery
Exercise places considerable stress on muscle fibres.
Repairing and rebuilding these fibres requires an adequate supply of essential amino acids.
Protein quality is often more important than simply feeding more protein.
Excellent protein sources include:
- Soybean meal
- Whey protein
- Lucerne (alfalfa)
- Lupins
These provide essential amino acids such as lysine, the first limiting amino acid in most equine diets and one that is critical for muscle development and repair.
Does Timing Matter?
Research suggests muscles become particularly responsive to amino acid uptake during the early recovery period following exercise.
Providing a source of high-quality protein within the first 30–60 minutes after strenuous work may help support muscle repair, particularly in young horses, horses building muscle, or those undertaking repeated high-intensity training.
While the exact timing window continues to be investigated, ensuring adequate high-quality protein is available during recovery is considered beneficial.
Don’t Forget the Hindgut
Recovery isn’t just about muscles.
The trillions of microbes living in your horse’s hindgut also need to recover.
Stress, dehydration and changes in feeding routines can all affect the hindgut microbiome.
Maintaining:
- Plenty of good-quality forage
- Consistent feeding routines
- Adequate water intake
- Appropriate fibre intake
helps keep the digestive system functioning efficiently and supports overall recovery.
Practical Recovery Checklist
After intense exercise:
Allow your horse to cool down properly before feeding.
Offer unlimited access to fresh, clean water.
Replace electrolyte losses according to the amount of sweat produced.
Feed good-quality forage as soon as the horse is comfortable eating.
Feed concentrates containing processed grains within approximately one hour if additional glycogen replenishment is required.
Include a source of high-quality protein to support muscle repair.
Return to your normal feeding routine as soon as practical.
The Bottom Line
Successful recovery begins the moment your horse finishes competing.
Replacing water and electrolytes restores hydration, replenishing glycogen prepares the horse for its next workload, and providing high-quality protein supports muscle repair and adaptation.
Most importantly, never overlook the importance of forage. A healthy hindgut microbiome underpins digestion, energy production and overall health, making fibre one of the most valuable components of every performance horse’s recovery programme.
Feed thoughtfully, recover effectively, and give your horse every opportunity to perform at its best.
