Warkentin, Tierney blaze through water in Nite Moves swim

In one of the fastest Nite Moves of the season, U.S. Olympian and Santa Barbara local Mark Warkentin held off Australia’s Heydn Tierney in a blistering 1k ocean swim on Wednesday at Leadbetter Beach.

Warkentin, who competed in the open-water swim at the Beijing Olympics in 2008, finished Wednesday’s race in 11 minutes, 55 seconds. Tierney, an ocean lifeguard and avid open-water swimmer in Australia, finished in 11:57.
