I'm pretty sure the answer is no. We had this thread on this a while ago

but wanted to make sure.
Also, does anyone know why we started running the 1600 in the US?
Way back were tracks in the US and England all imperial and then when we switched to metric we decided it was easier to run 4 laps, than figure out where the mile started, or to run a 1500?
