I was running at my local track today, and I noticed how the surface had a lot of cushion and provided a lot of friction for good footing. I started to think about what it would be like if a tennis court was made using this surface and it seems like it would provided a lot of benefits. It's a gritty surface and would play quite slow. Many experts suspect that European players are surpassing American players partly because the Europeans play on clay, a slow surface. It forces them to achieve a high shot tolerance and learn to construct a point. Another benefit the surface would provided would be longevity. The track I run on has been there for years and has no cracks and has not been resurfaced in at least ten years. Hardcourts, on the other hand, seem to begin cracking within 2 or 3 years. So, why are there no courts made using a rubberized surface? Are there in fact courts similar to this surface that I am not aware of?
