Rhythmic gymnast Jones stands in 21st place in the individual all-round competition after two rotations – the ball and the hoop – and the six-time national champion finishes with the ribbon and the club tomorrow.
And the 21-year-old, who was not expected to finish among the top ten finalists, is hoping to put her sport on the map.
She said: “I'm not really thinking about positions so for me it's just about doing the best I can and showing rhythmic gymnastics in this country is here and hopefully will inspire a lot of people.
“It was probably the most overwhelming competition I have ever done. I knew there was going to be a lot of support but that much blew me away.
"I was happy. There's always more you can do but with how nervous I was I was pleased with how it went overall. My target is just to be pleased when I come off the floor.”
Jones finished the day with a score of 48.750 as Russia’s Daria Dmitrieva tops the leader board on 57.800.
A score of 24.550 for her ball routine saw Jones get off to a solid start before 24.200 on the hoop set her up for tomorrow’s finale.
Rachel Smith, meanwhile, admitted Britain’s rhythmic gymnastics team are just happy to be competing at London 2012 and hopes she can raise the profile of her sport.
The team missed a target score set by British Gymnastics to prove they could compete at the Games, but won an appeal to ensure they could fulfil their Olympic dreams on home soil.
And after finishing the first day of the competition in 11th place, Smith insists she will be happy regardless of the outcome.
“What we've been through is pretty stressful,” said the 19-year-old.
“We hope the British public have been watching and we hope to raise the profile of the sport. That was our gold medal – qualifying.”
Team GB scored 24.150 for their routine with the five balls and will complete their campaign with three ribbons and two hoops tomorrow as Russia lead the way with 28.375.
And team member Francesca Fox admits that her team see London 2012 as a way of proving they can compete with the best.
She said: "Today we showed everyone what we can do. We haven't had our full time to train as we've had to spend time getting fundraising. If we had funding who knows what we could do.”
