The British star was bidding to break the world indoor 800 metres record – set on the very day she was born – at Saturday's Keely Klassic, which was set to be her first race since winning gold at the Paris Olympics last August.
Keely Hodgkinson was left in tears after being forced to abandon her world record attempt at the event named in her honour because of a hamstring injury.
She was due to race in the indoor 800 metres to try and break a 23-year record at the Keely Classic.
'I’m absolutely gutted that I won’t be able to race for the fans, especially after so many have bought tickets to see me try and break the world record.
Her injury news came shortly after a row had erupted over the BBC’s decision to only stream the Keely Klassic on iPlayer, preferring to show a repeat of the film Mr Malcolm’s List on BBC Two, followed by an old episode of Flog It!.
