Cyclist Sarah Storey and swimmer Jonathan Fox have won Great Britain's first two Paralympic gold medals of London 2012.
Storey triumphed in the women's C5 3km individual pursuit final when she caught her opponent Anna Harkowska of Poland just over the halfway point.
She said: "To get the gold medal is a dream come true."
In the Aquatics Centre, Fox stormed to victory in the S7 100 metres backstroke race.
Both Storey and Fox had set new world records earlier in the day when qualifying for their finals.
The medal success didn't end there. Cyclist Mark Colbourne won GB's first medal of the Paralympics when he took silver in the time trial event.
There were swimming silvers from Nyree Kindred (100m backstroke) and Hannah Russell (400m freestyle).
Ben Quilter took bronze in the -60kg judo.
