When the Olympic Games were awarded to London in 2005, the English Cross-Country Association immediately decided that it would be fitting to hold the 2012 event in the capital as it was the South's turn to hold the event. English Cross Country Association secretary Ian Byett told Athletics Weekly: "The City of London were keen to put it on and the staff and management at Parliament Hill always give tip-top cooperation in staging the event." The Junior Women's National Cross-Country Championships were held on a course of 6km.
After the charge up Kite Hill Gemma Kersey (Basildon AAC) was leading and after a mile Yorkshire and Northern champion Jennifer Walsh (Spenborough & District AC) led a group of 10. At the halfway stage Emelia Gorecka (Aldershot, Farnham & District AC) hit the front and only Walsh stayed in contention. Annabel Gummow (Bristol & West AC) overtook Walsh at the back of the course. With a mile of the race left Gorecka had a 50 metre advantage over Gummow who was clear of Walsh. Gorecka triumphed in 21:02 with Gummow second and Walsh third.
This was Gorecka's sixth successive National individual victory and her first junior women's title and Gorecka told Steve Smythe at Athletics Weekly: "I love the National and running at Parliament Hill and I'm over the moon to win for the sixth time in a row. The race plan was to start comfortably and see how I felt and early on I just tucked into the back of the leading group. I felt very good when I made my move and the races have gone well this year at Edinburgh and South of England Championships."
