Charlotte Broughton made it three wins from three starts as she confidently defended the leader's jersey in the under-16 section of this season's National Trophy.
The Countesthorpe rider produced a near-perfect tactical race on a flat Durham course to get the better of Beeline's Emily Wadsworth in a sprint finish.
Broughton, the MG Décor all-rounder, was at the front throughout the race, with national mountain bike champion Wadsworth the only one of her competitors able to stay with the pace.
However, she could do no more than hold Broughton's wheel.
Broughton's extra power was always likely to tell in the closing stages, and so it proved as she sprinted to the line to claim a comfortable victory and extend her 100 per cent record in this year's trophy.
Welsh rider Jess Roberts came in third and is now in second place in the overall standings.
Broughton, though, holds a substantial 30-point advantage at the halfway stage of the series.
Round four will be staged at Milton Keynes Bowl on December 1.
Welland Valley Wheelers' James Garrett has hit an excellent spell of form in the West Midlands League.
Garrett won the junior section of the league's ninth round, staged at Leicester Leys and promoted by Leicestershire Road Club.
It was his third win from the last four WML starts in what is proving a real run of consistency as the cross season gathers pace.
It was a convincing success, too, as Garrett hit the front early in the proceedings and set about building a substantial lead all the way to the line.
Victory in the senior race went to Rugby Velo's Luke Markham.
He had the company of Peter Banham (Fred Williams Cycles) for the first half of the race, but went clear when he put the hammer down after halfway.
