FIH have only approved use of this style pitch in events that do not require teams to train, and compete daily for more than 3 consecutive days. Also no case study has been completed on the effects of leaving this style pitch down for a month will have on the surface underneath.
Surely BOCOG would be happy to do a relay of the turf when the games are over? If the ground underneath's somewhat compacted that's a challenge a good groundsman should be able to handle.
