Parents of Paralympic medallists James and Libby Clegg explain how they watched James compete in the swimming pool before running to watch Libby on the track, before running back again to watch James receive his medal.
Loughborough-based sprinter Libby Clegg says it is a "great honour" to take part in the Paralympic Games.
Clegg, who took double gold at the European Championships in June, is looking to upgrade her Beijing silver when she competes in the T12 100 and 200 metres in London.
The 22-year-old has an eye condition known as Stargardt's disease, leaving her with only slight peripheral vision in her left eye. She is registered blind.
Clegg, who won 100m gold and 200m bronze at the 2011 IPC World Championships in New Zealand, says she hopes the understanding she has built up over the past two years with her guide runner Mikail Huggins can inspire her to Paralympic gold.

"Mikail and I run as a team, it's like doing a three-legged race where you're attached at the wrist rather than at the foot.
"We have to have a lot of communication. It's vital I have him, he is my eyes on the track. When I run I can't really see anything. I don't know whereabouts on the track I am, I can't even see the finish line.
"We spend quite a lot of time with each other so it's important we do like one another. If we didn't get on on a personal level then it could affect the way we run."
