After some sightseeing and promotional appearances, Phelps took in a second night of swimming at the Palau Sant Jordi before heading back to the U.S. on Tuesday. He's accompanied by his new girlfriend, Golf Channel reporter Win McMurry.
Phelps was still seething about the U.S. loss in the 400-meter freestyle relay on Sunday. The American were edged at the finish by the French, a repeat of last summer's Olympics when a team that included Phelps also settled for silver.
He said the Americans should have gone with a different lineup, using Jimmy Feigen in the leadoff spot and Nathan Adrian as the anchor. Instead, Adrian went first and Feigen took over for the finish despite being the least experienced member of the U.S. foursome.
"We should never lose that race," Phelps said.
