Routledge first encountered the sport after her coach discovered a para-standing tennis festival in Roehampton, south west London, last November.
“We met all these other people who were exactly like me… it was the most amazing day,” Routledge said.
Eager to play more, Routledge and her coach Donna Andrews found competitions across the world.
The 20-year-old has known her coach for 14 years and said she has been a “huge part of the journey”.
Ms Andrews, who has previously worked with career grand slam and Paralympic champion Alfie Hewett, said: “Georgia did so well and has been rewarded for all the training she had put in pre-tournament.”
“She is so grateful for all the help from everyone in Norfolk who have contributed to her success.”
