you just need to play sprinter miler and dirty urara FIRST get them to 3sparks (train them toward 700+ xxx 600 xxx 600, 600 give u 5% chance of getting 3 stars)

short track character require less stamina to run. they are easier to train for new account

-----------------------------------------------------------------------------------------
and then use 3+3+3=9 spark legacy to train so called "hard career" they suddenly become cakewalk

9 star on pwr means 63 free stat on the start of the game, and u would get another 63 every year

which would make it very easy on training them toward 700 600 600 440 600 breeder/bucket build (for farming 3star sparks)

King Halo, Rice Shower, Grass Wonder

1. Super creek, super moody, debuff in early campaign and a recovery unique skill.
2. King halo, moody, couple of different length if I remember correctly.
3. Grass wonder, I don't know why but I often avoid to play her campaign.

Special mention: The campaign isn't hard by any standards, but just extremely annoying to play for me, haru urara, barely any races to do, throughout her campaign you can only do like 3 optional G1 and they never go for more than 10k fans (I struggle to reach her unique skill upgrade caps, most of time you just do some G3 with like 7/8k fans at the end with the boost), extremely unconsistent runner and objectives are bad 3 fan goal check and an arima kinnen where you will most likely finish 16th and earn nothing from it (they should've at least made it earn fans like it was a first place or something).
I hate her campaign, and it's the best character to farm dirt sparks with ....

1. Maruzensky (due to few turn and early 1st place requirement in derby)
2. Gold Ship (I admit, I might not cut it as End chaser trainer)
3. Daiwa Scarlet (balance stats make me confused what she supposed to be good at)

glad im not the only one who absolutely suffered trying to get through grass wonder's career LOL

The toughest one for me so far has been Winning Ticket.

She's basically Rice Shower, but with worse growths, a less reliable personal skill, stronger rivals, and improbably terrible luck.

Not only is the the only Uma I've failed a 2% training with, she's done it MULTIPLE TIMES.

The only upside is that she seems really good and pulling the claw machine for some reason.

I can't really decide on a 2. and 3, because the last 7 runs I've done have all been Winning ticket - I finally completed her career on the last try, so uh, lucky number 7 I guess?

Biwa has been bit tough for me, but not like "I give up" tough

There are no difficult careers, at least when you start to understand the direction in which you need to work for different distances and running styles. There are very complicated careers.

Of these (at least of the characters that I have):

1st place.
Haru Urara. It is kinda difficult to get the required number of fans to increase the level of the ult, and at the same time maintain training. Most likely due to the strong limitation of her tracks only to dirt. Of which there are apparently not so many that can give a big boost to fans in one run.
And also I rarely play her because, in general, she does not good at collect the fans that are needed to increase the club rank. I have one generally so-so Haru for running Team Trials, and I am waiting for when I finally pull out another dirt runner to replace her.

2nd place.
Super Creek. Overall, there is nothing difficult with her, but her debuff at the beginning of the career can play tricks on you RNG, and with bad luck it can be problematic. Although, her late buff compensates for the initial risks quite well. So, overall, it's not a bad option, but it's tricky.

3rd place.
King Halo - if you want to prepare her for sprint. If you are preparing her for medium or mile, then it's fine. But in the absence of alternative candidates, preparing her for sprint is quite a complicated task because her career is full of medium tracks.

1. Haru Urara
2. Mejiro Ryan
3. El Condor Pasa
Even in Speed focus they still fall behind.

1. Rice - i win her once with random bullcrap deck. after try to reach A rank with proper deck and internet guide, shes being emo alot and ruined the career. but thats mean i cannot stop train my daughter, never give up!

2. Mejiro McQueen - idk what problem with her... already push speed until B yet still being so slow. maybe training issue lol

3. Mejiro McQueen skin - same above

I still have trauma from playing maya 6 times in a row... haven`t touched her since.

currently mejiro ryan is my problem child.

I agree with that.
I like the character and her personality but having so many low-graded races and barely any races especially at the beginning is quite annoying.
Luckily I somehow managed to get a 2*-spark for dirt with Taiki Shuttle and then managed to transform that into a 3* dirt-spark with El Condor Pasa so I can use both of those to train additional dirt-runners and I'm also waiting for Smart Falcon as she's another dirt runner.

@topic:
1. Biwa Hayahide
-> Struggled more than I liked to admit although she starts out as a 3-star and I had good enough parents. May not be hard per se but she also represents tropes I dislike which also affects my opinion towards her.

2. Makitanefukukitaru
-> So many random mood down-events and on top one can get "bad" race goals (e.g. performing mile-races with only a C-aptitude)

3. Grass Wonder
-> Like Fukukitaru way too many mood down-events

1. biwa (she's kicking my ass)
2. makitanefukukitaru
3. rice shower (she's so moody sob)
