Discover how Friendship Training works in Umamusume: Pretty Derby and how it can be improved further with upgrades.

While beginning a new career in Umamusume: Pretty Derby, players choose two Legacies and six Support Cards to assist and build their trainee. While the Support Cards provide various bonuses for training the stats they are stacked on, their true potential is hidden until Friendship Training is unlocked. This guide explores how Friendship Training—also called Rainbow Training—is accessed and improved in the game.
How To Unlock Friendship (Rainbow) Training in Umamusume: Pretty Derby?

Unlocking Friendship Training is linked to increasing Friendship Bonds. A Support Card’s bond with the trainee is indicated by the bar under their icon. Choose the stat the support card appears on during training to increase the bond.
Once Friendship Bonds reach 80% of their capacity, the bar turns orange and Friendship Training becomes available for that card. Friendship training activates randomly and a circle with glowing rainbow colors appears around the Support Card’s icon.
Since Friendship Training provides a large stat bonus to training, you should aim to unlock it for all cards as soon as possible. Ideally, all Support Cards should have Friendship Training available by the first Summer Camp or the second goal race. The exact bonus provided usually starts from around 10% for unupgraded cards and reaches a maximum of 35% after fully uncapping. Friendship Training multiplies the stat increase after other bonuses like “Training Effectiveness” and “Mood Bonus” have already been applied.
