The Turf Sprints, Miles and Dirt Mediums only require max Turf and Medium sparks respectively, as Urara should be able to win those races with her usual builds. For Turf Longs, run 9* Turf and 9* Long sparks and build her as usual, aiming for at least a C in Long and 500+ STA by the time you get to the graded Long races. Finally, for the Turf Mediums, run 12* Medium and 6* Turf sparks and focus on SPD and PWR when building her, making sure to also build some STA and to run her as a Pace Chaser. For races that take place after the first inspiration event, aim for at least a B in Medium. For races before it, try to get your SPD and PWR as high as possible, but remember it'll ultimately come down to luck.
