British eventing is easy go to home page and enter horses name or rider surname or you can google bdwp which is a similar thing ( Burghley Direct Web Page ) and then type in horses name or rider , I find it a good system and very transparant as it is warts and all
BDWP will also give future entries
BSJA will give notional and actual winnings which seem a bit pointless as they dont tell you if a horse has won that in a year or it has won it by going out 5 days a week and had every pole down along the way
