Walsall swimmer Ellie Simmonds says she is "shocked" by her performance in this morning's 400m freestyle heat.
Ellie smashed the Paralympic record by more than 20 seconds during her S6 400m freestyle heat, with a time of 5:24.64, as well as breaking her own European record and securing her personal best (PB).
The 17-year-old from Walsall was narrowly outside the world record as she made her intentions clear during the heat, booking a probably final showdown with American Victoria Arlen.
Ellie is the defending champion in the event. The final is due to take place at 17.50 tonight (1 September).
