If you choose to train points higher than 40 x your level, the extra training will become intensive training and will cost you 20 horseshoes per training point. Each training session will also give 1 bonus training point per level of your training course so upgrade your training course when possible.

If you win a challenge competition, you will get competition horseshoes. Competition horseshoes are payment for upgrading your training courses and your stable.

Each of your horses has a breeding value shown below the heart next to each of your horses. The breeding value is the total of the training points divided by 3. If you have at least 2 horses with a breeding value of 10 or more, you can get a breeding effect when you breed them. Breeding 2 horses will produce a new horse, but you will lose the 2 horses you used for the breeding. The new horse will keep the average training points from the parent horses.
