My name is Jamie Glick, and this piece is about running track surfaces. Running track surfaces are important to know about, because you want to know what kind of cushioning you're gonna have under your feet, and how to prepare yourself best when you're starting to run on a track. The first types of running tracks were built in the 1950s and 60s, and these were asphalt-based tracks. But these tracks required a lot of maintenance, they fell apart easily, they had to be resurfaced and releveled quite often, not very cost effective in the long run. After that they moved to a cinder-based track. And the cinder-based tracks while better and a little cheaper to make, they became hard in the winter and soft in the summer, and didn't really provide the cushioning that today's tracks would be able to provide. So the trend recently has become to make tracks made of rubber, latex or polyurethane. A rubber or latex track holds up better, provides better cushioning, and much less maintenance than one of the other asphalt or cinder tracks. Now the rubber and latex you also have the opportunity to change the color as much as you want, and you can have different depths of rubber or latex depending on how much cushioning you would like. The highest end track is called a polyurethane track. Now the polyurethane tracks are for world class track meets only, you probably will not find this track in your high school or your local park. The type of track used more often right now are rubber and latex. When you have a rubber track, you have the option of using what they call virgin rubber, which is untouched rubber, just used for the track, or recycled rubber. Now recycled rubber would be a little bit cheaper. And you also have the option of having different colors to conform to your team or your neighborhoods favorite color.
