muwhahahaha ignore tidus his celestial weapon you mad damn its the easiest to get exept yunas you just need to get the crest directly after yunalesca the rest is friging easy i love the chocobo race i always make sure i get in score a litle lower each time for more items and when i grow tired of it i finish it its so easy seriously a few pointers:

DONT use the analog stick use the buttons
press L 1 and 2 and R 1 and 2 this WILL make stearing your chocobo easier it is said to be a rumor but it truly works
and if in the beggining of the race the balloons arent on your side quiet
have a friend to count your balloons if you do not get hit you do about 40 seconds for the race so that maens 14 balloons and each time you hit a friging bird count another one

verry easy really i find wakkas harder cause i am still working on the stupid status reels and i already did 20 tournaments and 10 leauges after the attack reels and i dont even want to talk about kimarhis serious if theres one you you shouldnt get its that one
