All-weather running track
An all-weather running track is a rubberized artificial running surface for track and field athletics. It provides a consistent surface for competitors to test their athletic ability unencumbered by adverse weather conditions. Historically, various forms of dirt, grass, sand and crushed cinders were used. Many examples of these varieties of track still exist worldwide.
Measurement of a track
The proper length for a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead some are legacy to imperial distances like 440 yd (402.3 m). Prior to rule changes in 1979, distances in Imperial units were still used in the United States. Some facilities build tracks to fit the available space. Olympic tracks in the early 20th century were of other lengths. Each lane of the track could (by IAAF rules should) be as wide as 122 cm (4.00 ft), though the majority of American tracks are built to NFHS high school specifications that allow smaller lanes. The IAAF also specifies a preferred radius for the turns at 37 metres, but allows a range. Major international level meets are conducted and world records are allowed to be set on tracks that are not exactly 37 metres, but do fall in the range.
Starting in the late 1950s, artificial surfaces using a combination of rubber and asphalt began to appear. An artificial warm up track was constructed for the 1956 Summer Olympics in Melbourne, Australia. During the 1960s many of these tracks were constructed, examples still exist today. Their survival are a testament to the durability and inconsistency of these early attempts.
In the mid-1960s Tartan tracks, surfaced with a product by 3M. The name Tartan is a trademark, but many have misused it as a genericized trademark. This process was the first to commercialize a polyurethane surface for running tracks, though originally conceived for horse racing. Many Tartan tracks were installed worldwide including at many of the top Universities in the United States. Among that list was a Tartan track installed in the Estadio Olímpico Universitario, home of the 1968 Summer Olympics at Mexico City which were the first global championships to use such a track. Olympic shot putt champion Bill Nieder was instrumental in developing the product and selling it for this first use in the Olympics. An all-weather surface has become standard ever since. Another Tartan track was installed on a temporary basis for the 1968 United States Olympic Trials held at altitude at Echo Summit, California, before being moved to South Tahoe Middle School, where it survived for almost 40 years. An original Tartan track is still in place (though horribly mistreated) at "Speed City" San Jose State University on a satellite to the campus at 10th Street and Alma. Years of the abuse of tractors tearing it and cars parked on it shows the durability of this original product.
Surfacing tracks has become an industry with many competitors.
- Tartan; The legacy of the brand is now known as Tartan APS 
- Chevron 440; was a popular surface of the mid-1970s
- Rekortan; was invented and used for the 1972 Summer Olympics in Munich, Germany  and is still licensed Worldwide
- Eurotan 
- Martin ISS  was another 1970's development which now goes by the name of the manufacturer Beynon
and there are other techniques that distribute small chunks of rubber then adhere them in place with various Polyurethane or latex substances.
The International Association of Athletics Federations (IAAF), international governing body of the sport, publishes very specific regulations for the conduct of a Global Championship or International level track meet (which is their jurisdiction of the sport).
Since its inception in the early-1980s, the manufacturer of the surfaces selected for most championship meets has been by the Italian company, Mondo, again the trademarked brand name becoming misused as a genericized trademark. Mondo surfaces differ from the particles stuck in adhesion techniques, in that they are more of a rubber carpet, cut to size then tightly seamed together (in the linear direction along the lane lines). This form of construction gives a more consistent bounce (or energy return) and traction. Because of the tight fit specifications required for manufacture, construction surrounding these sites also has to be of a higher standard, making Mondo also one of the most expensive systems to use. Examples of Mondo tracks were used for the 1996 Summer Olympics (since removed from the Centennial Olympic Stadium) in Atlanta, Georgia, USA; 2004 Summer Olympics in Athens, Greece; 2008 Summer Olympics in Beijing, China and 2012 Summer Olympics in London, United Kingdom. Estádio Olímpico João Havelange, the future home of the 2016 Summer Olympics also has a Mondo surface.
Another player in the marketplace is BASF owned Conica, which can boast the 2009 World Championships in Athletics in Berlin, Germany (where Usain Bolt improved his 100 meters and 200 meters world records), along with other record hosting venues like Stadio Olimpico in Rome, Italy
