British wheelchair racer Hannah Cockroft has set a fourth world record in three days while competing in her season-opening events.

Her time of 52.80 seconds improved the mark she set in 2021 by 1.19 seconds.

On previous days, the 30-year-old had beaten her own 200m, 800m and 1500m world records in the T34 category.

Cockroft will next compete in the World Para-athletics Grand Prix event in Dubai, which begins on Sunday, as she prepares for July's World Championships in Paris where she will race over 100m and 800m.
