But that is the case with many thoroughbreds Bustino. Our Dancing Brave granddaughter (sadly deceased) was very immature when we got her and only began to look the real deal when she was about 5
Seriously though, that's because most horses have been on the go since they were barely 2 and not fully developed. Also, of course, most horses (by definition) aren't good enough to win anyway. Late developers that are very capable and therefore worth continuing with are few and far between. But if they are good enough they will improve up to age 5. JB is only 4 and lightly raced
I'm sure you are right in everything you say Ron, though I do have a slightly different view on 2yos. As regards Alpinista she was a lovely filly who bloomed as a 4yo. In fact after Torquator Tasso won the Arc a lot of discussion centred on Alpinista having beaten him and that if entered she'd probably have won the Arc. She didn't have to improve to win her Arc. I'm pro stayers and if more races were truly run more horses like Jan Breughel and perhaps Lambourn would be the stars of the sport. It is very worrying that we have not had many outstanding horses in the last 20 years. What has gone wrong?
