Barbara was a great athlete herself but didn't have enough funding unlike Jenny. Thanks to the National Lottery Jenny has been able to fulfil her ambition and talent and compete in this year's games.
The Mill's 3D Lead Artist Alex Hammond explains: "Our brief was to create a stadium worthy of holding an Olympic athletics event with thousands of spectators. We went through a few iterations of the stadium, either by adding tiers or making them bigger and in this way we could fill up the stadium to make it look as impressive as it does."
Looking back at the hopes of Barbara and forward to the hopes Jenny, take a look and good luck Jenny!
