Good on him for doing something.
Impossible to comment on it with out riding it and you're a bit out of my neck of the woods. However, in the pic above, the berm on the RHS (big one) doesn't *seem* to have a roller in or out of it?
From the pic it *looks* big, pedally and jumpy. That's not my idea of a PT, more a BMX track / jump loop. Not that it doesn't look fun 😎 PT's to me are tracks where you only need to put a few crank turns in then it's possible to ride round and round using only pump (effectively chainless). A good, fast track might involve some jumping (see McCormacks Bible and the progression of techniques to develop mega-speed).
Whatever though, anything someone's got off their ass and done themselves is good in my book 😎
