Bradshaw was involved in gymnastics from the age of six until she was 11, when she decided to try running. It was not until she was 17 that she tried pole vaulting for the first time.
Bradshaw's Junior career took off when she broke the British Junior pole vault record in June 2010, with a vault of 4.35m. A month later, she competed at the 2010 World Junior Championship, in which she was the favourite for the gold medal. However, she failed to vault higher than 4.15m, resulting in a bronze medal behind Angelica Bengtsson and Victoria von Eynatten, who vaulted 4.25m and 4.20m respectively.[6]
Bradshaw's first competition of the 2011 season was the 2011 European Indoor Championships, where she finished 11th in the qualifying round, with a best vault of 4.45m. Later in 2011, she represented Great Britain in the European Team Championships, where she finished in 5th place.
In June 2011, Bradshaw set a new British U23 record with a 4.53m vault at the British Under-23 Championships in Bedford.[7] However, just 5 days later, she set a new British senior record of 4.70m.[8]
In January 2012, Bradshaw improved the British indoor record by clearing 4.87m in Villeurbanne, during a Perche Élite Tour meeting. This put her third on the world all-time list, behind Yelena Isinbayeva and Jenn Suhr, and also third all-time for indoor performances. At the same competition she made her first world indoor record attempt at 5.01m, but failed.[9] Later that year, on 11 March she won a bronze medal at the World Indoor Championships held in Istanbul.[10]
Bradshaw competed in the 2012 Summer Olympics in London. She managed to reach the final, but knocked the bar at 4.55m, causing her to crash out of the running for a medal. However, she managed to finish in the top 8. In an interview with BBC Radio 5 Live, Bradshaw said that she was disappointed but that "by Rio, I will be at the top of my game." Bradshaw won gold at the 2013 European Athletics Indoor Championships in Gothenburg with a height of 4.67m in a jump off with Poland's Anna Rogowska, both having previously jumped 4.72. She later stated in an interview that she could have shared gold with Rogowska, but chose to jump off to be the lone winner of the gold.[11]
In 2015, Bradshaw vaulted 4.55 m to be selected in the British Team to the World Championships. At the World Championships in Beijing, she cleared 4.70 m before failing at 4.80 m. With this height, she finished 7th in the final where the Cuban Yarisley Silva took the gold medal with a jump of 4.90 m.
2016
Bradshaw competed in the Rio 2016 Summer Olympics, jumping 4.60m to advance to the final. In the final she cleared 4.70m on her second attempt but failed her three attempts at 4.80m and finished fifth.[12] She almost cleared her last attempt at 4.80m but in the last moment the cross bar fell to the ground.[13]
After the Olympics, she competed in 2016 Diamond League in Zurich, winning first place with 4.76m.[14][15]
2017
Bradshaw participated in many of the 2017 Diamond League meetings, and also reached the finals of the Diamond League in Brussels. She set a new personal best outdoors in Manchester in the same year at 4.81m. She participated in other notable events of pole vault around the world that year, which secured her a place in the 2017 IAAF World Championships in London in front of the home crowd, where she ended up 6th with a jump of 4.65m, and she lost the bronze medal only on count back. She has been hoping to seek glory that was taken away from her in the 2012 Olympic games in the same stadium, and afterward said she would focus on the 2018 IAAF World Indoor Championships in Birmingham. She also won the national outdoor championships in 2017.[16]
2018
Bradshaw started her 2018 indoor season in February, competing in the Perche Élite Tour meet in Rouen, France, where she won with a clearance of 4.60 metres[17] before going on to clear 4.70m on 30 March at an outdoor competition in Australia. As one of the favourites for the pole vault title at the 2018 Commonwealth Games on the Gold Coast,[1][18] she finished fourth with another clearance of 4.60m.[19] After clearing a season's best of 4.72 metres on 8 July in Rottach-Egern, she went on to win the biggest outdoor title of her career on 14 July 2018, when she won at the inaugural Athletics World Cup in London, improving her season's best to 4.75 metres. She further improved her season's best to 4.80 metres on 17 July in Jockgrim, before winning a bronze medal on 9 August at the European Championships in Berlin, with another clearance of 4.75 metres.[20]
2019
Bradshaw had a good start in the early 2019 by winning the indoor nationals with a jump of 4.80m in February.[21] She was selected for the 2019 IAAF World Athletics Championships in Doha, Qatar, reaching for the final with a single jump of 4.60m in qualifying.[22] She subsequently finished in fourth place in the final.[23]
At the British Championships, Bradshaw cleared a new British record height of 4.90 m, her record has since been surpassed by Molly Caudery.[25] At the delayed Tokyo Olympics, Bradshaw won the bronze medal with a jump of 4.85 m.[10]

While competing in the qualifying competition for the 2022 World Athletics Championships, Bradshaw's pole snapped and she was forced to withdraw from the competition.[26]

Bradshaw participated in the 2024 Summer Olympics, but did not proceed past the qualification round of the pole vault.[27][28]
