The mother of missing Madeleine McCann is to take part in a charity run to raise money to help find missing people.

Kate McCann will join other families whose loved ones have disappeared for the Miles for Missing People run through Hyde Park, in London.

She will run alongside Nicki Durbin, whose 19-year-old son Luke vanished in 2006 in Ipswich, and the sister of former Manic Street Preachers guitarist Richey Edwards, who went missing from a hotel in London, in 1995, aged 27.

Kate said: "I'm running the Miles for Missing People for all missing children.

"Gerry and I know the pain that having Madeleine missing has caused us, but sadly we are not alone.

"There are thousands of families across the UK waiting for news.

"That's why Missing People provides support for missing children, vulnerable adults and families left behind, and we want to do all we can to help.

"We will be raising money for the charity's vital work and we hope people around the country will join us as we remember missing children everywhere."

Madeleine went missing from a holiday resort in Praia da Luz, in Portugal, in May 2007.

The run will take place on Saturday and is expected to attract nearly 500 people to the capital for the 6.2-mile (10K) event.

It is sponsored by Friends Reunited and marks the beginning of a new partnership between the social networking site and the charity Missing People.

Martin Houghton-Brown, chief executive of Missing People, said: "We're so grateful for the support shown by Kate and Gerry McCann, Nicki Durbin, Rachel Elias and all the families taking part in Miles for Missing People, and our hope is that this event will allow us to improve and expand our services to thousands more families living in limbo just like them."

Last year, the charity received more than 123,000 calls for help.
