Can make it work even without spending money

I'm playing without spending any money, but I managed to win G1. To get straight to the point, high-rarity broodmares and special? feed, along with training, are really strong. With a weak horse using normal feed and training, it takes about 10-15 weeks to get a 1.1 odds favorite in G3. However, if you use a horse produced from a high-rarity broodmare with special feed and training, you can get a favorite with odds below 2.0 in G1 within 4 weeks.
