A schoolgirl from Northampton features in a new Nike advertising company after clocking up the fastest sprint time for a 10-year-old.
Savannah Morgan was approached by Nike after she competed in the Minithon in London last October.
She ran 60m in 8.50 seconds but it was only later that her family realised her time was the quickest in the country.
In the months after, Nike got in touch with Savannah by first making contact with her sister, Corinne Humphreys, who made the Great Britain squad at last year's Commonwealth Games.
It led to Savannah taking a two-day trip to Amsterdam in July for a photo shoot for Nike's Back to School campaign.
Now Savannah's images can be seen on the giant screens outside Nike Town on Oxford Street and other outlets, as well as the Nike website.
The company, which has made her a Nike Ambassador, sent a creative design team from America to spend the day with Savannah at Nike Town for her input into what trainers she likes and for what occasion.
They also joined her at one of her training sessions in London to meet her teammates and handed out gift vouchers.
Savannah, of The Bartons Close in Dallington, recently broke three county records for her age group in the 75m, 150m and long jump.
She has also been selected to run in the under-13s relay at the Müller Grand Prix in Birmingham this Saturday.
At the next Minithon in October, Savannah is hoping to beat the current world record of 7.96 seconds before she turns 11.
Her talents were first flagged up by her headteacher at St Mary's Catholic Primary School after beating boys and girls in sports day races.
Mum Amanda McKenzie Morgan said: "I think Savannah is just naturally gifted. We think she's on course to do great things if she sticks with it.
"Athletics is something she really wants to do - she's tried lots of things like dancing and zumba but athletics is the one thing she's stuck with.
"The trip to Amsterdam for the photo shoot was amazing. They wanted to get certain photos of her so they followed her about, taking pictures. It felt like we were on a film set.
"My husband works near Nike Town in London so he's seen her on the adverts and we've had messages from people to say they've seen her too."
Savannah trains every Friday with a specialist sprint coach at the Lee Valley Leisure Centre in Enfield and every Tuesday with Northampton and Rugby Athletics Club.
Earlier this year, Savannah appeared on Sky's Game Changers show after being filmed and interviewed at school.
