Sarah Harding

Hundreds of people, including three members of Girls Aloud , gathered in Hyde Park to take part in a memorial run for Sarah Harding .

The Singer , 39, died in September, a year after revealing she had breast cancer.

Bandmates Nicola Roberts , Cheryl and Nadine Coyle were at The Race For Life For Sarah, a 5k Cancer Research run.

A huge pink-clad crowd took part in London, and others, including Kimberley Walsh , joined in remotely.

Cheryl, who now uses a mononym and was previously known with the surnames Tweedy, Cole and Fernandez-Versini, has said she still cannot quite believe the death of her bandmate.

She Said : " It doesn't feel like she's gone at all. To be honest, I've never experienced or anticipated this grief.

" You know, I've lost grandparents when I was younger and I lost a friend when I was younger but nothing like this, The Feeling of shock and disbelief and it still lingers now to be honest. I still can't quite believe it's real. "

Nicola Roberts spoke of Harding's " electric" personality: " Sarah's energy was like a firework so I feel like that huge difference in energy when she's not there.

" I think that for us right now, we don't feel like Girls Aloud . We don't feel like A Band without Sarah. She, like I said just now, she was such a huge part of our energy that it doesn't feel like that. "

Nadine Coyle said she was " in denial" about bandmate Sarah Harding 's illness: " This Time Last Year we were actually hanging out.

" We all met up Last Year . She was there and we were talking and she didn't even seem that sick.

" I was in denial the entire time and was The Friend that was 'Oh, it's gonna be all right', you know, I was completely in denial right up until The Day she passed. "
