Jessica Long and Brad Snyder of Baltimore won races Friday at the IPC Swimming World Championships in Glasgow, Scotland. Long led from the start and swam away with the gold for her sixth world title of 2015 in the women's 400 freestyle S8 race. The three-time Paralympian and world-record holder in the event touched the wall in 4:47.95 to finish nearly 14 seconds ahead of Great Britain's Maddison Elliott in second. For Long, 23, a 17-time Paralympic and 29-time world medalist with three more events in Glasgow, winning isn't taken for granted. "Especially as I get older, I appreciate each [medal] more and more because it's gotten harder to continue winning," she said. "I think it's awesome to get to the top, but staying there is a whole different thing. For whatever reason I've been able to stay at the top for a long time and I'm really grateful." Snyder posted a personal-best time in the men's 50 freestyle S11, touching the wall in 25.78 seconds. Snyder won the 100 freestyle and 400 free on Monday and Tuesday, respectively. Snyder, a Navy veteran who lost his vision one year before winning Paralympic gold in 2012, also set a championship record in each race. "Losing my vision took away my ability to serve in the U.S. Navy but the way I see it, I still serve my country by being a part of Team USA, so that's really important to me," Snyder, the 2012 Paralympic silver medalist in the 50 freestyle said.
