izziesmum, if you're competing at higher levels, grooms will usually braid/tack up/cool out your horse. My boyfriend explained that it's a lot easier both on the riders and the grooms, if a lot of people from one stable are going, so they don't have to keep track of who to take care of and who to leave alone.
