Amy Hughes

In 2017, Hughes claimed to have broken the 7-day treadmill world record, by running 521 miles (838 km) over seven days at the Trafford Centre, more than the previous record of 517.63 miles (833.04 km). Her claim was rejected by Guinness, was subsequently heavily scrutinised and met with scepticism by some in the running community, in particular on Let's Run's forum, and the Ultrarunning Community Facebook group. Criticism was largely focused on the lack of any verifiable data to support this or any previous record claims, limited evidence to suggest the requisite athletic pedigree to break a record previously held by elite runners, and video evidence of Hughes taking breaks whilst the treadmill continued to run. Her record claim had no independent witnesses, with the only witness being her ex-partner Dave Keighley.

By making unsubstantiated and unverified claims of completing 53 marathons in 53 consecutive days, Hughes claims that she broke the world record for most consecutive marathons; according to the Guinness Book of Records, the current women's record is 60, set by Alice Burch in Southampton, England in 2015, and the previous women's record was 17, set by Parvaneh Moayedi in 2013. Hughes also raised over £42,000, of which £10,000 was donated to the Neurosurgery Department at Alder Hey Children's Hospital.

After completing the marathons, Hughes was involved in a number of high-profile events. She helped Blue Peter presenter Lindsey Russell train for the London Marathon, and has spoken at many Running Expos. Her record won the "best running moment of the year" at the 2015 Running Awards.

She started her first run on 6 August 2014, in Chester. From Chester, she travelled from north to south and then to the south-west, before travelling north and completing her 53rd marathon in Manchester on 27 September. Covering a total of 1,400 miles (2,300 km), Hughes travelled to cities including London, Liverpool, Wolverhampton, Newcastle, Glasgow, and Cardiff. After the event, Hughes said her highlight was Brighton, and that Tunbridge Wells was "hilly". During the attempt, Hughes suffered from stomach viruses, one of which caused her to take 8 hours to run her 35th marathon around Taunton.

A subsequent investigation website concluded that "As a result of her treadmill record being denied, people have questioned her ability. 520 miles on a treadmill in 7 days would require an ability on par with the elite ultra runners and multi-day runners. While she will not be able to have this record validated, there are many sanctioned multi-day races – or even 24-hour races where she could at least validate her abilities. To date, none of her official races stand out. She admits that she is not fast, but she can prove her stamina in any # of sanctioned events".

Amy Hughes (born 1987) is a British marathon runner. In 2014-15, Hughes claimed to have completed 53 marathons in 53 days, after which she claimed to have broken the Guinness World Record. However, her record claim was rejected by the organisation, as their requirements at the time asked for claimants to have run the marathons in official races. In 2017, Hughes claims to have broken the 7 day treadmill world record, by running 521 miles (838 km) over seven days at the Trafford Centre. Her record claim was rejected as implausible for a non-elite runner, and it also lacked independent verification.
