The IAAF does prescribe a range of "force reduction" (the amount of energy the track absorbs and does not return to the athlete) between 35% and 50%; a surface which falls outside that margin is not considered acceptable (and might also feel uncomfortable to the athletes). | |

It can be a mix and match of things like rubber, polyurethane, cork, synthetic materials, etc. The underpinning material beneath the surface also has an impact on performance (plywood, fiberglass, etc.) | |
| Feb 6, 2016 at 1:43 | comment | added | pjmorse | This is all true, and I've heard about the relative hardness of the Atlanta track firsthand. Supposedly this is why Haile Gebrselassie declined to double back in the 5,000m after winning the 10,000m. However, this all pertains to the oval for running events; the OP is asking about the runway for the horizontal jumps. | |
