I’m Emrys Williams and this July, I'll be representing Great Britain in the Under-24 Men's Underwater Hockey squad at the World Championships in Turkey - my second time competing for GB, and this year I've also been selected as vice-captain. It's an incredible honour, but the programme is completely self-funded by us as players. I don't expect anything at all, but any support - however small - genuinely helps me get there.

Even if you know of any businesses or companies that might be interested in sponsoring, I'd be really grateful for any connections or suggestions.
