A Comprehensive Guide to Modern Athletics Track Surfaces

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 SurfacesModern synthetic running tracks typically consist of multiple functional layers, with two primary materials dominating the industry. 1. Polyurethane (PU)

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.

Key Benefits: Excellent wear resistance, elasticity, and weather resistance

Applications: Professional athletics tracks, school running tracks, and training facilities.

The Jrace Sport Solution: We provide innovative two-component polyurethane materials with low odor and a safer formulation, providing reliable material support for competition-grade sports facilities. 2. EPDM Rubber Granules

EPDM (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.

Key Benefits: Excellent resistance to ultraviolet radiation (less prone to fading) and good compatibility with polyurethane materials for strong, durable bonding.

Design Flexibility: Modern running tracks are commonly designed in red, blue, green, and other colors, providing both functional performance and greater flexibility in track design.

The Jrace Sport Solution: We provide 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 the most common types:

Full PU Running Track

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

Characteristics: Because the entire structure uses PU materials without the addition of elastic rubber granules, these systems provide more consistent elasticity, excellent durability, and uniform athletic response.

Applications: Suitable for professional training facilities and high-level competition venues.

Project Case: 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

These systems combine the advantages of different materials and are among the most widely used running track systems. This structure provides a balance between athletic performance, service life, and construction cost.

Typical Structure:Top Layer: PU Top Coat + EPDM Granules

Base Layer: PU Layer with EPDM/SBR Granules

Applications: Widely suitable for schools, training facilities, and public sports facilities.Spray Coat (Breathable) Running Track

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

Characteristics: 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.

Advantages: Flexible installation, convenient maintenance, and a relatively high level of cost-effectiveness.

Applications: 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.

Installation Requirements: Because the track material is prefabricated and formed in advance, the substrate must meet higher requirements for flatness, slope, and material hardness.

The Jrace Sport Solution: Our 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. The surface layer provides spike resistance, weather resistance, aging resistance, and slip resistance.

Durability: Using industrial-grade rubber with a service life of more than 15 years, the system is resistant to sun exposure and color fading. It delivers stable physical performance for professional competition-grade facilities. Jrace Sport's prefabricated tracks have been used globally, including at selected venues for the National Games of China.

How to Choose the Right Track Surface?

When selecting a running track system, several key factors should dictate your choice:

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

Budget & Frequency of Use: For sports facilities with high usage frequency, track systems with stronger wear resistance and more stable structures should be considered.

Climate: Local temperature, rainfall, and UV exposure affect material selection. For instance, breathable tracks (Spray Coat) are excellent for rainy regions due to efficient drainage, while highly UV-resistant EPDM surfaces are ideal for areas with heavy sun exposure.
