The role of racing surfaces in horse welfare - Current trends and future challenges
/Words - Virginia Lisco
Every thunderous stride of a racehorse is a delicate balance between power and vulnerability, and the surface beneath their hooves can make all the difference. Whether it’s turf, dirt, or synthetic tracks, these surfaces aren’t just where races are run, they play a critical role in protecting the health and welfare of the horses. The composition, maintenance, and resilience of these surfaces directly impact the likelihood of injuries, affecting everything from joint strain to catastrophic breakdowns.
In an era where the welfare of horses is more scrutinised than ever, the choice and upkeep of racing surfaces have become critical. Turf requires precise irrigation and aeration to remain safe and consistent; dirt demands meticulous grading and moisture control to prevent compaction; and synthetic tracks, though engineered for uniformity, must be closely monitored for temperature sensitivity and degradation over time.
But the challenges don’t stop there. With climate change rewriting the rules of weather patterns, bringing heavier rains, harsher droughts, and rising temperatures, the very nature of these tracks is being put to the test. Maintaining consistent conditions under these shifting extremes will require innovation and a commitment to sustainability, as the racing industry navigates the intersection of performance, safety, and environmental responsibility.
Traditionally, turf tracks dominate the European horse racing scene, serving as the primary surface in most racecourses due to their ability to provide optimal conditions for racing, particularly during the milder months.
However, in recent years, there has been a growing interest in synthetic surfaces, across Europe, where these tracks are gaining traction for their ability to withstand the challenges posed by winter weather. Major racecourses across the continent utilise synthetic surfaces like Polytrack and Tapeta to ensure safe and consistent racing even under adverse weather conditions. Synthetic tracks are particularly valued for their superior drainage, stability in cases of frost and heavy rain, and different maintenance requirements compared to turf, offering a practical and modern solution to tackle climate challenges while maintaining a continuous racing calendar.
Dirt tracks are now almost entirely absent in Europe, with rare exceptions at a few minor racecourses where the quality of racing is generally low. This is because dirt surfaces neither provide the technical advantages of synthetics nor carry the prestige and tradition associated with turf. The shift toward synthetic surfaces, particularly noticeable in regions with harsher winters, is gradually establishing itself as a key trend for the future of European racing, while the dominance of turf remains unchallenged for the most prestigious events.
The ongoing shift in surface preferences reflects a broader focus on equine welfare, a priority that has spurred significant research and collaboration among leading organisations in the racing industry. The adoption of synthetic tracks, driven in part by studies highlighting their safety benefits, is a direct response to growing concerns about horse injuries and fatalities. A key driver behind this shift is the safety record of synthetic tracks compared to other surfaces.
Data from studies, such as those conducted by The US Jockey Club's Equine Injury Database (EID), provide critical insights into this trend. According to the EID, synthetic tracks report significantly lower rates of catastrophic injuries, approximately 1.2 incidents per 1,000 starts, compared to dirt tracks, which average 2.1 incidents per 1,000 starts, and slightly lower than turf tracks, which average 1.6 incidents per 1,000 starts. These findings underscore the uniformity and predictability of synthetic surfaces, which minimise variability in footing and reduce the risk of uneven impact during high-speed gallops. Additionally, synthetic tracks are less susceptible to environmental factors, such as extreme wet or dry conditions, which can compromise the performance and safety of both turf and dirt surfaces.
Several prominent organisations have dedicated substantial resources to studying the relationship between track surfaces and equine health. For instance, The US Jockey Club, through the EID, has compiled data since 2008 that consistently demonstrates the superior safety profile of synthetic surfaces, providing a foundation for their increasing adoption, particularly in regions with demanding climates or high year-round racing schedules.
Similarly, the British Horseracing Authority (BHA) conducts comprehensive reviews of racecourse safety, ensuring that maintenance protocols and track designs align with welfare goals.
In France, France Galop has implemented robust injury monitoring systems, using the insights to refine track conditions and better match surface types to their environmental contexts. These efforts underline the growing recognition that track surfaces play a pivotal role in reducing injury risks, particularly in the high-impact phases of a horse's stride, as detailed in research such as the Equestrian Surfaces Guide. Despite the demonstrated safety advantages of synthetic surfaces, debates remain regarding their long-term impact on equine health. Critics suggest that synthetic tracks may contribute to soft tissue stress injuries due to their firmer composition compared to well-maintained turf.
Building on the findings of the Equestrian Surfaces Guide, it becomes evident that the biomechanical interaction between the horse and the track surface is a critical determinant of safety and performance. Each phase of the stride: landing, support, and rollover, introduces distinct biomechanical stresses that vary based on the surface’s composition, maintenance, and environmental conditions.
This research, further supported by Dr Mick Peterson’s, Racing Surfaces White Paper, highlights the importance of not only selecting appropriate surface types but also ensuring consistent maintenance to reduce injury risks.
Peterson’s study provides a detailed analysis of how surface properties, such as firmness, cushioning, and grip, directly influence the forces acting on a horse’s legs during high-speed galloping. The white paper emphasises that well-engineered synthetic tracks excel in delivering predictable and uniform performance, mitigating the variability often associated with dirt and turf surfaces. For example, in the landing phase, when shockwaves and braking forces are transmitted through the leg, synthetic tracks are designed to provide a controlled level of slide, dissipating some of the impact forces and reducing stress on the hoof and distal limb. In contrast, surfaces with excessive grip, such as poorly maintained dirt, amplify these forces, increasing the risk of injuries.
During the support phase, when the hoof absorbs up to 2.5 times the horse's body weight, surface uniformity becomes critical. Peterson’s research underscores that uneven surfaces, like waterlogged or overly compacted turf, can lead to uneven load distribution, raising the likelihood of strain injuries to tendons, ligaments, and joints.
Synthetic tracks, with their engineered shock-absorbing properties, excel in maintaining stability during this phase, effectively minimising these risks. The rollover phase, where propulsion forces peak, also places significant demands on grip and shear strength. Synthetic surfaces are particularly effective here, offering consistent traction to prevent slips while avoiding the overstress on tendons and ligaments caused by overly hard or high-grip surfaces.
In addition to biomechanical insights, Peterson's white paper emphasises the importance of consistent surface maintenance. Even the best-engineered tracks can lose their safety advantages without proper upkeep. The study highlights the need for regular monitoring of moisture levels, compaction, and grip, alongside the use of advanced tools like surface testing equipment and ground-penetrating radar to proactively identify and address hazards. By maintaining these standards, synthetic surfaces can sustain their intended performance and safety benefits over time, reducing injury risks for both horses and riders.
These findings align closely with real-world injury data, such as that collected through the EID, which shows significantly lower rates of injuries and fatalities on synthetic tracks compared to dirt and turf. Peterson’s work further supports this data by demonstrating how the controlled grip, shock absorption, and uniformity of synthetic surfaces mitigate the extreme forces associated with high-speed galloping.
As racing organisations increasingly prioritise equine welfare, integrating these biomechanical insights and maintenance best practices into surface design is becoming essential. This evolution not only addresses safety concerns but also ensures that performance standards are upheld across diverse environmental conditions and year-round racing schedules.
Another pressing challenge tied to track surfaces and horse welfare is the impact of climate change, which is increasingly complicating the maintenance and safety of racing tracks. Extreme weather events, such as heavy rainfall, prolonged droughts, and unexpected temperature fluctuations, threaten the integrity of turf, dirt, and even synthetic surfaces. Maintaining tracks in optimal condition under these conditions is not only a logistical challenge but also critical to equine welfare and the continuity of racing schedules.
Turf tracks, which dominate the European racing landscape, are particularly vulnerable to these climate pressures. Heavy rainfall can waterlog turf, reducing its ability to provide a stable and uniform footing. Prolonged droughts pose a different but equally severe threat.
In 2022, during an exceptionally dry summer, several racecourses in the UK, including Newmarket, faced challenges in maintaining adequate irrigation. The lack of rainfall led to concerns about the firmness of the ground, which can increase the risk of injuries to horses. To address this, racecourses have had to rely heavily on irrigation systems, though these solutions come with significant costs and raise concerns about water sustainability in drought-prone regions.
Dirt tracks, though rare in Europe, face their own set of challenges under extreme weather conditions. Unlike synthetic tracks, dirt surfaces are highly susceptible to changes in moisture levels. Heavy rains can turn dirt tracks into dangerously muddy and slippery courses, increasing the risk of falls and injuries. Even synthetic tracks, while more resilient to climatic variability, are not immune. Extreme heat can affect the surface properties, potentially leading to inconsistent footing. This highlights the need for ongoing innovation in synthetic surface technology to enhance resilience under extreme temperature conditions.
As climate change intensifies, the industry faces an urgent need to adapt its infrastructure and maintenance practices. Investment in weather-resistant technologies, such as hybrid turf systems that combine natural grass with synthetic reinforcement, is one promising avenue. Additionally, many racecourses are exploring more sustainable water use strategies and heat-resistant materials to future-proof their tracks. While these measures require significant financial and operational resources, they are crucial to maintaining the safety and sustainability of horse racing in an increasingly unpredictable climate.
At its core, the quality and maintenance of racing surfaces are fundamental to ensuring the safety and performance of both horses and jockeys. The interaction between a horse’s stride and the track is critical, with every phase: landing, support, and rollover, subjecting the horse’s legs to significant forces that vary depending on the surface type. This makes the choice and upkeep of racing surfaces a cornerstone of the sport.
While turf continues to dominate prestigious events for its tradition, aesthetic appeal, and performance characteristics, synthetic tracks are increasingly recognised for their ability to minimise injury risks, maintain consistency across diverse weather conditions, and meet the demands of year-round racing.
Insights from organisations like The US Jockey Club and BHA, combined with research such as Peterson’s Racing Surfaces White Paper, underline the importance of balancing innovation and tradition in surface design and maintenance. Synthetic surfaces, with their engineered properties, offer uniformity and controlled shock absorption, mitigating the biomechanical stresses that lead to injuries.
However, turf’s natural cushioning and long-standing association with the heritage of the sport ensure its continued dominance at elite racing events. Maintaining this delicate balance is essential to enabling horses and jockeys to perform at their peak while prioritising safety and welfare. As the industry adapts to modern challenges, including climate variability and evolving performance demands, racing surfaces will remain central to ensuring the sport’s longevity and sustainability for future generations.
