Lots of access to water (mine wont drink at shows unless they're seriously thirsty, but I have it available anyway), try to find a spot with shade, keep off her back when you don't need to be riding (you see lots of riders who never get OFF their horses, but just sitting around on your horses back is when soreness is going to pop up, movement distributes your weight). For my jumper I get witch hazel in a spray bottle and spray his legs (fronts and backs, but more so on the fronts) and his back after we're all done, as does my coach.
Check your tack regularly, loosen up your girth when you don't need it tight (I made the mistake of leaving it tight last show and ended up with some issues from the heat). And don't overdo your warm ups! I saw lots of riders warming up over fences for close to half an hour yesterday. Get their legs and minds working and then you're good to go.
