Racing Riku (ビーチレース, Bīchi Rēsu?, lit. "Beach Race") is a mini-game in Kingdom Hearts, involving racing Riku around the island. It takes place on Destiny Islands during the second day. The outcome of the race determines the default name of the Gummi Ship. If Riku wins, it will be named Highwind. If Sora wins, it will be named what the player enters before the race.
The course runs through the cove of Destiny Islands where a zip-line can be taken or the long route towards a star-shaped tree and then back. The star will glow once the half marker has been reached. Players cannot cheat by hitting Riku as use of the Wooden Sword is disabled. Riku may take the zipline if Sora blocks his path, but at certain intervals of the race Riku will walk instead of run.
First, make your way across the wooden platforms. Be careful, as one of them will fall if stepped on. Although this step can be useful, jump as soon as you step on the platform, if the timing's correct, Riku will fall instead, slowing him down. Next, climb up the ladder and zip-line down. This should put you in the lead, but don't get cocky. Hurry over to the star-shaped tree and touch it. Now turn around and jump on the tops of the trees. This is the hardest part and takes a lot of patience. Jump from treetop to treetop, making your way to the side of the tower. Finally, run across the platforms towards Kairi.
Alternatively, instead of going across the wooden platforms, hop down from the starting point and run through the water to the other side and continue across the beach. Once you reach the slope jump onto the first ledge followed by the second ledge and proceed to platform your way to the star shaped tree. This should put you in the lead. Now, drop down and make your way back across the beach, jump up the ledge, then use either the wooden platforms or go through the water to get back to Kairi. This method requires less precise platforming, but allows Riku to run unimpeded, requiring Sora to be as fast as possible to win.
After winning the race, Sora will receive a Pretty Stone.
