Richard was first up with a stunning performance to win the 200m (T42 class) in the Olympic Stadium on Saturday.
After a slow start, Richard stormed through the field to beat his own world record in 24.38 seconds and clinch the gold.
He said: "Everyone was shouting my name, there was so much support, 80,000 fans roaring me to success and they are part of this.
"The race was exiting. The start was slow, I built around the corner and then exploded on that last 120 metres. As I was coming up to the lead two, I put on the afterburners because of the crowd's support. It was was mind-boggling."
Rower Pam took her place in the LTA mixed coxed fours alongside David Smith, James Roe, Naomi Riches and cox Lily van den Broecke at Eton Dorney on Sunday.
They held off the challenge of Germany to strike gold.
"I'm overwhelmed and the thing that stood out the most was the crowd cheering and willing us forward," said Pam.
"It felt like we weren't just doing it for ourselves, but doing it for the whole nation. It was amazing."
