The "guy with the orange hair" is Ichigo Kurosaki. The guy you're talking about with flowers as a weapon must be Byakuya Kuchiki- he has a metal ornament in his hair (it's a symbol of his high status in the Kuchiki family). Byakuya Kuchiki's zanpakuto is Senbonzakura, or "Thousand Cherry Blossoms". In his offensive attack, he literally fights with a thousand cherry blossoms.
And I don't know about racing, but they did fight, and there was a lot of flash-step involved. In otherwords, they were trying to outrun each other, and half the fight was a test of speed.
