What do you mean by ‘at Wimbledon’? Commentators? Players? Officials? The crowd?
The commentators, players and umpires are from all over the world. The crowd are mostly from all over the UK, with quite a lot from overseas too. You will hear plenty of regional accents there. A London accent is a regional accent, for a start, so even if the entire crowd was local to Wimbledon itself, most of them would have a regional accent.
Your accent is no more special or interesting than any other accent. Do you want a medal for it or something?
