There is a problem. Unless you are born with a silver spoon in your mouth, you aren't going to be able to find the trainers and ponies at this level.
For a competition pony suitable, you are looking at €40,000+
Then you have to get the trainers.
That costs even more.
The issue I find in Germany is we have an abundance of lower level horses who are OK trained, with OK trainers.
But if you want to get anywhere, you need to money. You need to be able to afford the horse or pony to buy or ride, and the trainer to take you the distance.
I can't comment on the UK as I have never experienced the horse world there.
This young lady has also done very well for herself. But she has the one GP horse, knowing she cannot afford another 'finished' one so has three younger horses on the back burner. Again, there is still a lot of money Jenny Lang and Loverboy with Mutual Love and Respect to the Top | eurodressage
Honestly, I love my riding. I love dressage. Would I want to compete against some of the people out here with what I would be able to afford horse and trainer wise? Not in a month of sundays.

All of the above are 30,000+ and no where near the 'top' for competition levels out here so far... just as a guide.
