Kate McCann's Bike Challenge
Madeleine McCann's mum's completed a five hundred mile charity bike ride from Edinburgh to the Tower of London - to help other families with a missing loved one.
Kate McCann (pictured centre) has described how her daughter Madeleine "was very much on my mind" throughout the 500 mile ride.
Mrs McCann was greeted by her cheering husband Gerry and their two children as she completed the ride on Wednesday 17 June 2015.
She was joined by up to 20 other cyclists to raise money for charity Missing People, of which she is an ambassador.
Mrs McCann said: "It's such a great feeling to have achieved that.
"We all know why we're here, we know it's such a good cause and that keeps you going whenever you're going up a hill and you can't see round that bend - you just keep thinking about those children.
"I know this won't help Madeline but I'd hate to think that any other child would have to go through this and their family would have to go through what we've been through.
"Although Madeline has very much been on my mind through this I know that that is helping lots of other children.
"The charity is fantastic and we've all come to realise what a lifeline they are to many people.
"For the last ten or 20 miles I felt quite emotional, I could feel it building up in my chest and then I saw (my family) waving, it was lovely to see them."
The group travelled through Newcastle, York, Nottingham and Northampton before crossing the finish line in London.
Mrs McCann last year launched Child Rescue Alert for the charity alongside the mother of murdered schoolgirl April Jones.
The scheme is designed to use social media, text messages, email and digital billboards across the UK in addition to traditional broadcast media to issue alerts when a child is believed to have been abducted, and so far more than 250,000 people have signed up.
Madeleine was three when she went missing from the family's holiday apartment in Portugal's Algarve on May 3 2007 and it has become one of the most famous missing persons cases of all time.
Missing People chief executive Jo Youle said: "We're really proud to support the McCanns and for them to support the charity and to keep the word going around about missing children, to keep the search alive for children and adults that are still missing."
