Fifty teams will be involved from clubs which include Uckfield, Crowborough, Heathfield, Hellingly, East Grinstead, Rye … and Jersey.
Ages of participants will range from Under 7s to Under 12s. They will play on 12 pitches.
Townspeople are welcome to go along to support the local club. The bar will be open, food will be for sale, there will be bouncy castles for children, and a day of watching mini rugby at its best is promised.
