Quite a few para-swimming World Records have been broken in the last few months.
The most recent:
Maddison Elliott (AUS, age 14), broke the S8 50m free WR at our National Age Championships a fortnight ago, then broke it again at National Open on Saturday. 30.28
For context, old Women's S8 50 free LC WR by Chinese swimmer Shengnan Jiang, 30.85
