Dobbin ran the first leg and teamed up with Imani-Lara Lansiquot, Dina Asher-Smith and Daryll Neita to clock a world leading time of 42.29 seconds.
The 27-year-old from Sprotbrough finished sixth in 23.06 in the women’s 200m final at the opening Diamond League leg in Doha earlier this month.
Dobbin made her Olympic debut at Tokyo 2020 – 14 years after an epileptic seizure left her unable to walk or talk. She was just 13 when she suffered the seizure at school and it took her months to fully regain her speech.
She was a part-time athlete until 2019, combining athletics with a job as a receptionist at Loughborough University’s sports facilities.
Dobbin is the daughter of former Celtic, Doncaster Rovers and Barnsley footballer Jim Dobbin.
