The Codebreakers Cup will be back on the 28th September 2019! The tournament, which takes its name from the World War Two heroes at nearby Bletchley Park, will once again be aimed at C grade teams.

2018 saw the inaugural Codebreakers Cup take place on Saturday 29th September and it was a roaring success, with Leicester Royals becoming the first team to lay their hands on the "Colossus" Trophy. Read the report here.


This year the tournament will be bigger and better, with an extra pitch, four additional teams and even an extra trophy up for grabs!


Visitors might know Milton Keynes for a few things, its concrete cows, a massive shopping centre and its remarkable ability to defeat even the most proficient map-reader with its multitude of roundabouts.

But in recent years, Milton Keynes has become known for its growing softball community. The Milton Keynes Diamonds have successfully taken part in slowpitch tournaments around the country and a hugely successful local league will enter its fourth year in 2019.
