Entered one of my 2 year old sprinters into the Nunthorpe in which it bolted up, but the jockey advice was to go for the BC Sprint at Ascot which is a 3YO and up race.

The jockey recommendation for the next race is based on a simple game code. Whatever the race is a prep for is what the jockey will tell you to aim for if you place in the top 3. To ask the game to discern whether your horse is even eligible for that race seems to be to hard. I'm still trying to get the game to stop running a game horse in two races on the same day.
