7th grader Jordan Hasay's 4:34.02 1500m is Youth Girls national record.
Looks like Briana J's got some competition - both are class of 2009. I bet this girl hasn't run 700+ races since she was 6. Did a simple yahoo search and came up with 4 results: 3 swimming meets and one track meet (above). I guess that 5K are group WR does not matter much if she never wins Footlocker.
