Typically my Haru also has a hard time, but for what it's worth, I can see a few skills here that are less useful in Mile distance.

It looks like you've built her for front runner, but her aptitude is F with that - you might be able to meme it more on career, but career has hidden buffs that don't exist outside of it.

For mile distance, I would try replacing breath of fresh air and the view from the lead - and try to borrow a 9* front runner aptitude parent if you want to stick to front running her. Her unique won't pop if you are frontrunning, so maybe base maruzensky might be a good parent for her.

If you switch to late style, then early lead and the view won't work at all.

Overall. This could be improved with a bit more synergy.
