Talented Tillie has a bright future ahead - it's just deciding which sport she wants to compete in!
Tillie, 15, is the Lancashire Schools Javelin Champion - she has won it for the last two years - and she also represents her county at rugby!
"I got into javelin during Covid as my sister went running and it was something to do at the track!" said Tillie, who competes for Burnley AC as well.
"I found I was quite good. My best is 30m but I threw 27m at the Lancashire Schools Championship in Blackpool recently to win it again.
"I also like 200m - I will take part in anything really!
"I also play rugby for Burnley and Lancashire Under 15s. I got selected for my county after tough trials. I play scrum half but also play No 10. I am just an all-round sports person!"
