There are just days to go until the 2016 Paralympic Games in Rio de Janeiro get underway - with the track cycling programme beginning on the first day of competition on Thursday 8 September.
The ParalympicsGB stars have been training at the Rio Olympic Velodrome in the run-up to the Games - and we've gone behind the scenes with the track cycling squad to see how preparations are going.
ParalympicsGB riders train in Rio
Kadeena Cox is making her Paralympic debut in Brazil - and she's set for one of the biggest challenges any athlete will face in Rio.
Cox will compete in two sports, athletics and cycling, and is aiming to become the first British Paralympian to win medals in multiple sports at the same Games since 1988.
Jody Cundy is in Rio searching for redemption. The 37-year-old will compete in his sixth Paralympic Games, and his third as a cyclist following success in the pool in Atlanta, Sydney and Athens.
Cundy was denied a restart in the 1km time trial at London 2012 in controversial circumstances - and says he's in Rio looking for his missing gold medal. His newly-designed prosthetic leg reflects that, with a pirate theme in search of buried treasure. Can Cundy strike Paralympic gold for the sixth time in Brazil, twenty years after his first?
As well as the 1km time trial, Cundy will also compete in the team sprint with Jon-Allan Butterworth (pictured) and Louis Rolfe. The trio claimed world championship gold and set a world record earlier this year in Italy. Butterworth will also tackle the 1km time trial, while Rolfe will take on the individual pursuit.
Crystal Lane makes her second Paralympic appearance, following her debut in London. Lane rides the 500m time trial and individual pursuit in the C5 classification, alongside Dame Sarah Storey - who heads to Rio as Britain's joint-most successful Paralympian, a title she could hold on her own with gold in Brazil.
Alongside Lane is Megan Giglia, the double world champion and world record holder who makes her Paralympic debut, competing in the 500m time trial and individual pursuit.
A duo making their first appearance at the Paralympics is tandem pair Steve Bate and Adam Duggleby. Bate and Duggleby are set for a busy Paralympic Games, competing in the individual pursuit before switching to the road cycling events.
Another tandem pair experiencing the Paralympics together for the first time is Lora Turnham and her pilot Corinne Hall. Turnham competed in London, but it's Hall makes her Games debut in Rio, with the duo racing in the pursuit on the track.
Three other tandem pairs will compete in Rio this week. Neil Fachie won gold and silver in London, but teams up with pilot Pete Mitchell for the first time at a Paralympics in Brazil for the 1km time trial on the track.
Craig Mclean is veteran of previous Olympic and Paralympic Games, winning team sprint silver at the Olympics in 2000, before piloting Anthony Kappes to gold in the Paralympics in London four years ago. He teams up with Games debutant James Ball for the 1km time trial in Rio.
Former world champions Sophie Thornhill and Helen Scott will race the 1km time trial and individual pursuit in Brazil. It's also Thornhill's Paralympics debut, although Scott has already won silver and bronze alongside Aileen McGlynn in London.
