Cockroft was born on 30 July 1992 in Halifax, West Yorkshire. She had two cardiac arrests after birth which left her with permanent damage in numerous areas of her brain, resulting in weak hips, deformed feet and legs and mobility problems and affecting the fine motor skills in her hands.[8] She is able to walk short distances but uses a wheelchair for long distances.[9]
Thompson went on to coach her for the first year of her career.[10] In 2008 a dance academy she attended gave the proceeds from programme sales at its annual show to help her buy her own racing chair, but when it arrived, its made-to-measure set up was incorrect, so her father, a welder, modified the wheelchair to fit.[11] After returning to the UK School Games that year, and taking gold in her first competitive 100 metres race, she was subsequently invited to join the Great Britain Paralympic Team shortly after the Beijing Paralympics.[10] In 2009, Cockroft participated in her first ever road race; the London Mini Marathon, taking the Champion title in the girls 14–19 age group category.
2010
By 2010, Cockroft was being coached by Peter Eriksson, head Paralympic coach at UK Athletics.[14] She again competed in the London Mini marathon, retaining her title as the female champion and at the Knowsley disability athletics challenge in May, she broke her first World Record in the T34 400 metres, recording a time of 65.51 seconds. Later that month, Cockroft sat her A-level exams and broke seven more world records in the space of eight days.[citation needed] At the Aviva and UK Athletics Awards in December, she received the Best British Paralympic Performance award for 2010.[citation needed]
2011
Cockroft made her senior Great Britain team debut at the age of 19, at the 2011 IPC Athletics World Championships in Christchurch, New Zealand. Here, she took gold in the T34 100 metres and the T34 200 metres.[15] Later that year she made her junior representative debut at the IWAS World Junior Championships, winning both the 200 metres and 400 metres. Her performances earned her a second Best British Paralympic Performance award in November 2011 and honorary lifetime membership of her athletics club, Leeds City AC.
2012
In May 2012, Cockroft became the first Paralympic athlete to break a world record in the London Olympic Stadium, recording a time of 18.56 seconds to win the T34 100 metres.[16] She broke the record again at the Swiss National Championships later that month, finishing in 17.60 seconds.
On 31 August 2012, Cockroft competed in her first Paralympic Games final and won Great Britain's first track gold medal since 2004, and first track and field gold medal of the 2012 Summer Paralympics, winning the final of the 100 metres T34 in 18.05 seconds, a Paralympic record.[17] On 6 September, she won another gold medal in 200 metres T34 in 31.90 seconds, also a Paralympic record.[18] In honour of her achievements at London 2012, Royal Mail issued two postage stamps featuring Cockroft and painted two post boxes gold in her home town of Halifax.[19][20] She was awarded the freedom of Calderdale at a homecoming event at the Halifax Piece Hall and was named an MBE in the 2013 New Year Honours.[21][22]
Cockroft was named in the 2013 BBC Sports Personality of the Year shortlist, coming 7th overall. She was the first Paralympian to ever be nominated for the award outside of a Paralympic year.[citation needed]
2014
In March, Cockroft competed in and won a Sport Relief edition of Strictly Come Dancing, dancing with Pasha Kovalev.[26] On 1 June, Cockroft recorded a new world-record time of 3.53.57 over 1500 metres during the Bedford International Games.[27]
In August, Cockroft took gold in 100 metres and for the first time competed in the 800 metres, winning gold at her first IPC European Championships that were held in Swansea. She later took her fourth title as British Athletics Para athlete of the year and was named Athletics Weekly female para athlete of the year.[citation needed]
2015
2015 saw Cockroft lose her first race in seven years, when she came second to British compatriot Kare Adenegan over 400 metres at the Newham open meet in July. She won the 800 metres later the same day. In Doha at the IPC World Championships at the end of the season, Cockroft retained her world champion title over the 100 metres, and won her first gold medals over the 400 metres and 800 metres, on a world championship stage.
In 2017, Cockroft raced over the 1500 metres for the third time in her career, breaking the T34 World record with a time of 3.50.22. She now held the full set of T34 World Records for the first time. At the same meet, held in Arbon in Switzerland, she also demolished her 400-metre World record set the previous year at the Rio 2016 Paralympic Games, and her 800-metre World Record, recording a new time of 1.55.73. In July, she returned 'home' to the QEII Olympic Stadium in Stratford to compete in her fourth World Championships. Although she had food poisoning the night before the T34 100 metres final, Cockroft powered home to take gold in a new world-record time of 17.18 seconds. She also became world champion over the 800 metres and 400 metres, making her a 10-time world champion and the most decorated British athlete in World Championship history. Cockroft was named British Sportswoman of the year by the Sports Journalists Association for her achievements. She was the first Paralympic athlete to ever win the award in its 57-year history.
2018
2018 saw Cockroft's first defeat on the international stage. After topping the podium for seven years, the 26-year-old won silver in the T34 100 metres at the World Para Athletics European Championships in Berlin. She then went on to regain her European Champion title over the 800 metres, after missing the event in 2016.
2021
In June 2021, Cockroft was among the first dozen athletes chosen to represent the UK at the postponed 2020 Paralympics in Tokyo.[31] At the end of June, she was in Manchester for the British Athletic Championships where she was first in a mixed classification 400 metres wheelchair race in front of Sammi Kinghorn and Mel Woods.[32] She successfully retained her women's 100 metres T34 Paralympic title after winning gold at the Tokyo Paralympics with a new world record timing of 16.39 seconds.[33] It was also her third consecutive Paralympic gold medal in women's 100 metres event and her sixth Paralympic gold medal.[34]
Personal life
Cockroft left her home and training base in Yorkshire to study journalism and media at Coventry University in 2013. She moved back to her home town of Halifax in 2016 to prepare for the Rio Paralympic Games. She has ambitions to work in television media after her athletics career.
In October 2014 she launched 17 Sports Management Limited ("17"), a sports management company.[35]
She cites Canadian wheelchair racer Chantal Petitclerc as her sporting inspiration.[36] Petitclerc, winner of 15 Paralympic gold medals and formerly coached by Eriksson, has been involved with Cockroft's development as a mentor and advisor.[37][38]
