Modern athletics tracks are not made from a single material. Instead, they are professional sports systems formed through different structural designs and construction methods using materials such as polyurethane (PU), EPDM rubber granules, and prefabricated rubber.

Jrace Sport, an internationally recognized supplier of competition-grade running tracks, has more than 20 years of experience in material development, construction guidance, and project services. In this article, we will introduce the characteristics and applications of different types of track surfaces.

Common Materials Used in Track Surfaces
Modern synthetic running tracks typically consist of multiple functional layers, with polyurethane (PU) being one of the most important materials.
In in-situ track systems, polyurethane PU materials are commonly used as the main track material. They are applied and cured on site to form an elastic sports surface. PU can also be used as a binder to bond rubber granules, forming an elastic base layer and a wear-resistant, slip-resistant surface layer.

Due to its excellent wear resistance, elasticity, ...
... and weather resistance, PU is widely used in professional athletics tracks, school running tracks, and training facilities.

Jrace Sport provides innovative two-component polyurethane materials with low odor and a safer formulation, providing reliable material support for competition-grade sports facilities.

EPDM rubber granules are another commonly used material for track surfaces. EPDM, or Ethylene Propylene Diene Monomer rubber, is typically applied to the outermost layer of the track and is mainly used to improve surface wear resistance, slip resistance, and visual appearance.

EPDM rubber granules offer excellent resistance to ultraviolet radiation, making them less prone to fading. They also have good compatibility with polyurethane materials, allowing for strong and durable bonding. Modern running tracks are commonly designed in red, blue, green, and other colors, providing both functional performance and greater flexibility in track design.

Jrace Sport provides highly weather-resistant EPDM rubber granules in a wide range of options. Particle size, color, and rubber content can be customized according to project requirements. The granules are durable, easy to install, and support the creation of vibrant and freely designed patterns.

Common Types of Track Surfaces
Running track systems can generally be categorized into in-situ systems, including Spray Coat, mixed, composite, and full PU systems, as well as semi-prefabricated and prefabricated systems.
Below are some of the most common types of running tracks.

Full PU Running Track
Full PU Running Track systems are primarily composed of polyurethane materials and are considered one of the higher-performance types of running track systems.

Because the entire structure uses PU materials without the addition of elastic rubber granules, Full PU Running Track systems provide more consistent elasticity, excellent durability, and uniform athletic response. They are suitable for professional training facilities and high-level competition venues.

In 2024, Jrace Sport constructed a Full PU Running Track at the National Stadium of Tanzania. The project was designed to meet the requirements of high-level international competitions and provide a true full-PU running track capable of meeting the requirements for World Athletics Class 1 certification.

Note: A true Full PU Running Track refers to a system in which the shock-absorbing layer is made entirely from Jrace Sport-UNITE-TECH Full PU material without the addition of elastic rubber granules.

Full PU Mixed Type Running Track
Full PU Mixed Type Running Track systems combine the advantages of different materials and are among the most widely used running track systems.

A typical structure consists of:
Top layer: PU Top Coat + EPDM Granules
Base layer: PU Layer with EPDM/SBR Granules

This structure provides a balance between athletic performance, service life, and construction cost, making it widely suitable for schools, training facilities, and public sports facilities.

Spray Coat Running Track
Spray Coat Running Track systems combine a rubber granule base layer with a spray-coated surface.

Due to their breathable structure, rainwater can drain efficiently, helping to reduce water accumulation on the track. At the same time, the rubber granule base provides effective shock absorption.
Spray Coat Running Track systems offer flexible installation, convenient maintenance, and a relatively high level of cost-effectiveness. They are commonly used for school sports fields and public sports facilities.

Prefabricated Running Track
Prefabricated Running Track systems are manufactured in advance as roll materials in a factory and then installed directly on site.
Because the track material is prefabricated and formed in advance, the substrate must meet higher requirements for flatness. Strict requirements also apply to the substrate slope, material hardness, and other installation conditions.

Jrace Sport prefabricated running tracks feature a precisely engineered two-layer structure. The bottom layer uses a specially designed structure and manufacturing process to achieve stable bonding with polyurethane adhesive while providing excellent shock absorption and vertical deformation performance. The surface layer provides spike resistance, weather resistance, aging resistance, and slip resistance.

Using industrial-grade rubber with a service life of more than 15 years, the system is resistant to sun exposure and color fading, while providing exceptionally strong bonding and resistance to cracking. It delivers stable physical performance for professional competition-grade facilities. Jrace Sport has provided professional prefabricated running track solutions to multiple countries, and Jrace Sport prefabricated running tracks have also been used at selected venues for the National Games of China.

How to Choose the Right Track Surface?
When selecting a running track system, several factors should be considered, including the intended use, budget, climate, and frequency of use.

School sports fields generally place greater emphasis on safety, durability, and maintenance costs, while professional competition venues focus more on athletic performance, material stability, and compliance with international standards.

Local temperature, rainfall, and UV exposure can also affect material selection. For sports facilities with high usage frequency, track systems with stronger wear resistance and more stable structures should be considered.

Conclusion
Jrace Sport, as an international competition-grade running track supplier, continues to focus on the development of high-performance sports surface materials and provides professional, reliable, and international-standard running track solutions to customers worldwide. Through scientific material selection and professional construction guidance, Jrace Sport helps customers create safer, more durable, and high-performance sports facilities.
