Loughborough College athlete Julie Rogers was one of the youngest competitors at London 2012 at just 13 years old but when she returns to the Paralympic stage in Rio, it will be for a different sport.
Four years ago Julie participated in the seated volleyball but on Saturday she turns her attention to the track to compete for ParalympicsGB in the T42 100m.
Despite switching to athletics only three years ago, the 17 year old Loughborough College Sport student is already ranked fifth in the world in a category for amputees.
Julie was born without the tibia and fibula in her right leg and had to undergo two amputation procedures so she could be fitted with an advanced prosthesis.
Growing up in a sporty family she was encouraged to be active and tried swimming, wheelchair basketball and gymnastics before finding sitting volleyball in 2010 and quickly establishing herself as a strong player.
Following selection for the Great Britain Rio squad, Julie said: "I knew I had the potential to go to Rio if I worked hard, so it's just really overwhelming that I've been selected.
"I've felt quite nervous about competition selection, but I never put any pressure on myself to make Rio. It was just sort of a bonus if I earned that spot.
"Athletics is a really competitive sport, especially in disability sport – there is a really high standard, so it was definitely good to prove that I deserved a space in the team.
“I started athletics because my brother was already at the track doing the hammer throw and I fancied a change of scene.
"I did both for a while before I realised I really did like the environment of athletics and as I trained for longer I realised I had quite good potential in it.
"I got talent-spotted, if you like, and I was given sponsorship for my running blade. I just went step-by-step from there; I got selected for a couple of World Juniors and it's all led to this."
Julie last year won bronze in the T42 100m at the IWAS World Games.
