I received a reply from the government department that deals with Sport, I didn't get a response from the MP herself but I got a response regardless!
The support team on their letter thanked me for details of the blog and they stated "it was a pleasure to visit the site and learn more about sandboarding", it's worth mentioning at this point that they are the relevant department for Sport; they don't endorse any sport but they have diverted my attention to Sport England which is an organisation that deals with the recognition, support, and funding for sports.
Armed with this new information, I have wrote a follow up letter to Sport England outlining what I want to see and how they can help me; in the response from the Department for Digital, Culture, Media & Sport a very important message was included: "in order to qualify for support and funding from Sport England, sandboarding would need to become officially recognised." and so it means that I have a plan, more or less.
To become a member of Dune Riders International, we must have facilities that complement the sand dunes in the UK; but to have the facilities we need money from small businesses, sponsors, grants, etc... And to get this, we need sandboarding to be recognised.
View the full letter below, as always I will keep you posted on what happens next.
