They made up nearly half of the total squad, which repeated the successes of the last three years.
The other athletes came from Amber Valley and Derby.
The winning teams will go on to represent the East Midlands Region in the National Finals at Birmingham NEC on Saturday.
This follows on from the County U11s also winning their Regional Final at the same venue in January.
