Thank you very much for replies.
I only have 3 or 4 horses to upload.
Can I upload the same horse but with different ages?
I'll try not to miss the upload window after week 5.

Have you played the game much? Breeding your own horses?
I'd try to get more horses for upload if you can.
2yo: 1 x 5/6f, 1 x 7/8f and 1 x 9/10f
3yo: 1x 5/6f, 1 x 7/8f, 1 x 9/10f, 1 x 12f, 1 x 14f
4yo: Same as 3yo and 1 x 16f and 1 x 20f horse.
Hope that helps? There are lots of threads on breeding and trailing using the race builder which should help.
