Heather Arneton of France.
She long jumped 21' 6Â¾" (6.57m) this year indoors at age 14. Her TJ best is 43' 8" (13.31 m). To put that in perspective for you, 6.57m would have ranked her #8 in the NCAA this year and 13.31m would be 16th in the TJ.
She's run 11.85 for the 100 (1.2 m/s wind) and a 11.59 wind-aided (3.5 m/s wind). Both marks were run at altitude in El Paso, TX of all places earlier this year.
