Very interesting quote below
This track is so fast, and if the heat comes it\'ll get faster. They might run (six furlongs) down there in six (1:06) and change. The thing is they don\'t know how to slow it down right now. If they put water in it, it compacts it and makes it harder. It winds up like adobe. I don\'t think that First Defence will run in six, but someone might.\"
