Team GB archers Alison Williamson and Larry Godfrey won their first National Series Grand Final titles in Oxford.
Godfrey, the best of the six home participants at London 2012 with a last-16 exit, ended team-mate Simon Terry's three-year reign as champion and has qualified for the World Cup Grand Final in Tokyo as a result.
Six-time Olympian Williamson lost in the first round of the Olympics but defeated Naomi Folkard to secure her maiden success in the competition.
"The Olympics was a big disappointment, but it wasn't to be," said Godfrey.
"Winning this title is a timely boost, and now I can concentrate on finishing the year strongly with a good performance in Tokyo - I can't wait, because I've had a great year, and was so disappointed I couldn't reflect that at Lord's."
Williamson added: "I'm delighted - this is our big domestic event of the year, we all want to win it, and to take the gold medal is a big thrill."
