 Grey Thompson is learning to speak Welsh |
Tanni Grey Thompson gave British athletics followers something to cheer when she won gold in the T53 100m on Thursday night.
But she made sure that her Welsh-speaking fans weren't forgotten either.
Straight after coming off track, the Cardiff-born athlete, who is now based in Redcar, showed another string to her bow.
She is currently learning to speak Welsh and managed a few words for BBC Radio Wales' Welsh news programme.
Tanni was also delighted that young daughter Carys was in the stadium to watch her mummy pick up a 10th Paralympic gold medal.
American tennis player Nick Taylor is bidding for Paralympic gold in Sunday's doubles final but his route to the top certainly hasn't been an easy one.
Taylor is the only player in the quad world top 10 who uses a power chair rather than a conventional sports chair.
In addition, he serves by throwing the ball up with his feet which certainly gets him noticed.
"Sometimes different is good and the way I serve attracts attention - it is especially popular with kids," he admitted.
Taylor teams up with David Wagner when they take on British duo Peter Norfolk and Mark Eccleston in the decider.
It isn't just the athletes who are working hard at the Paralympics - the worldwide media are doing their bit too.
But the combination of early starts and long days at the Games are starting to take their effect on many people and fatigue and forgetfulness are beginning to set in.
One media colleague went to a Paralympic venue on Thursday missing two vital items - accreditation and his belt.
The accreditation problem was sorted out but the missing belt led to some tricky moments during the day.
