i know high school results are not frequently discussed on this board, especially girls results for distances below the mile. nevertheless, i had to mention the outstanding performance of the eleanor roosevelt girls team at penn relays. according to the washington post, the first american girls team to ever win both the 4x4 and the 4x8 in the same year. 3:39 and 8:51.
