I have Increased Stamina III (15% less stamina reduction) from the hereditary skill, and Choco Reraise III for the other one. It enables me to spring the entire race even if I'm frenzied a couple times. The main issue I have is when it's always out front no matter how many traps it runs into/heavy being used on it, but over half the time I can't even target it due to having the NPCs gang up on me any time I am close to overtaking it.
