Olympic champion Jessica Ennis has made a last-ditch appeal to save the stadium where she was discovered as a teenager and still trains.
Councillors are expected to approve the closure of the Don Valley Stadium at a meeting later today.
Ennis said: "I've got some amazing memories, starting my athletic career there and having that iconic stadium in my home city is incredible.
"To lose that would be such a shame for future athletes coming through, so I hope that the right decision's made and we can find a way to keep it."
Olympic gold medallists Jessica Ennis, Nicola Adams and Greg Rutherford have arrived at Buckingham Palace to receive their honours.
Thousands of people lined the streets of central London today to watch floats, carriages, performers - and Jessica Ennis - in the Lord Mayor's Show.
The annual parade marked the inauguration of the 685th Lord Mayor of the City of London, Alderman Roger Gifford, who was carried through the capital in a golden coach.

The annual parade marks the inauguration of the 685th Lord Mayor of the City of London, Alderman Roger Gifford, who will be carried through the capital in a golden coach.
Joining him will be Olympic gold medallist Ennis who will have the pleasure of using a Jaguar F-Type sports car.
The car will take the athlete along the three-and-a-half mile route, which passes around Bank and Aldwych.
This year's show will showcase the talents of 6,500 people, 18 vintage cars, a tank and a steamroller among others.
Olympic gold medallist Jessica Ennis has revealed the extreme pressure of being the face of the London Olympics.
In her new book, Unbelievable, serialised in The Times, the heptathlete champion also described how she was bullied because of her size at school, and the "pure fear" she felt before the 800 metres, her final event at the Olympic Stadium.
Of the weeks and months building up to the Games, she wrote: "The pressure was huge. I would drive past five big posters of me on the way to training. It was still hard to take in.
"One night I was driving to a chip shop and was about to go in when I saw the huge Powerade ad hanging outside. There I was, supposedly sweating after a hard session, clad in Lycra and selling good health. I thought, 'God, I can't go in now', and drove on to Sainsbury's instead."
Olympic gold medallist Jessica Ennis is pretty nippy on the track, but that is nothing compared to her latest set of wheels.
The heptathlon star is taking part in this year's Lord Mayor's Show procession in the City of London and showed off the car that will take her around on November 10.
Ennis, 26, was especially good in the running events in the seven-discipline sport but said she got an adrenaline rush when the Jaguar F-Type hit 150mph on a test run.
Ennis, an ambassador for the Jaguar Academy of Sport, said: "I did get quite excited the other day when I was driving it - we got up to about 150mph and I don't think I can run that fast!
"It was a massive adrenaline rush, it's great to experience that kind of speed. But I don't think I'll be reaching that kind of speed anytime soon."
Olympic gold medallist Jessica Ennis has tweeted:
Sheffield United are set to rename one of their stands after Olympic gold medallist Jessica Ennis.
From this weekend, the Bramall Lane stand will be renamed The Jessica Ennis Stand in recognition of the Sheffield heptathlete's achievements.
Sheffield United owner Kevin McCabe said: "It is an appropriate and fitting tribute to re-name our Bramall Lane double tier stand after one of the finest athletes this country has ever produced".
Ennis told the club's website: "I never expected when I started out in athletics in Sheffield all those years ago that I would have a football stand at Sheffield United named after me".
Olympic gold medallist Jessica Ennis will be immortalised on the cover of The Beano as Ennis the Menace.
The heptathlete appears in a special edition of the comic which celebrates Team GB's success in London 2012.
