Wilson Hardy, 24, from Worthing, is part of a 12-player squad in Rio and it is the first time in 108 years that Team GB have had representation in rugby at Olympic level and a first for the seven-a-side format.
Great Britain play the hosts Brazil and then Japan in the group stages on Saturday, before they meet Canada on Sunday.
The quarter-finals also take place on Sunday, with the semi-finals and final on Monday at the Deodoro Stadium.
Wilson Hardy began her rugby career with Worthing aged 11 and played at Roundstone Lane until she was 17.
She is a former pupil at Worthing College and Our Lady of Sion and is hoping to return home with a gold medal: “In sevens rugby, anyone can beat anyone on the day and we’re 100 per cent looking to medal.
“It’s going to be a really strong competition and there will be six to eight top teams but we’re definitely hoping for gold and are not going to hide behind that.”
