SEWARD, Alaska — An Olympic buzz permeates an Alaska coastal community thousands of miles away from Japan and nearly a full day after Lydia Jacoby scored a major upset to bring home gold in the women’s 100-meter breaststroke at the Tokyo Games. Jacoby, a 17-year-old who will return for her senior year of high school in Seward, was the first Alaskan to ever qualify for the Olympics in swimming. “We were hoping for a medal, but for her to hit the wall first was just beyond any of our expectations,” said Sarah Spanos, a swim mom who volunteers with the small team that Jacoby belongs to, the Seward Tsunami Swim Club. “And just everybody’s beaming with pride and joy and just tears, lot of tears.”
