Ellie Edwards, 17, showed sparkling form to take the Greater Manchester under-20 200m title in Macclesfield.
The Maccabiah Junior gold medallist broke the tape in a personal best time of 25.69.
A delighted Edwards said: "This is the best I have felt in three years in terms of my fitness. If I stay injury free I can have a great season."
