I still would like to see the BNR and BNH division : ) I did my very first event a few weeks ago (horsies very first event too). I talked to a gal in my division who said she had been eventing for 20 years (apparently at higher levels 10 years ago) but who now qualified as a BNR. She did very well. Wow this is a tough sport (level of competition in BNR!). But I'm going to keep at it!
I think at starter HTs the BNR divisions can come up tougher than the BNH. At least, I have seen much lower dressage scores in the BNR division, that I assume are mainly dressage riders having fun at the lower levels.
