Captain Kathryn Janeway entered the Delta Flyer II in the race. O'Zaal informed her that the race was a step towards peace for the four cultures that lived in the area. There had been war between them for years, and this would be the first time the cultures were at peace.
O'Zaal had the difficult task of juggling all the political considerations of each culture involved with the event, given that the peace among the four species was still fragile after nearly a century of war. He knew that each decision he made might offend one of the species. To settle a dispute about which culture would host the pre-game reception, he accepted Janeway's offer to host it aboard USS Voyager.
When he found out that there was a possibility of sabotage, he considered canceling the race. He decided to continue, refusing to cave into extremists. Paris, Kim, and Torres stopped the extremist named Irina, who had planted a bomb, and the race was successful and the peace held. (VOY: "Drive")
