After serving in the Army, Warren opened Tug's Tavern, a sports bar and restaurant in San Diego's Pacific Beach that he owned for 17 years. The bar, beginning in 1975, sponsored the annual Tug's Swim-Run-Swim, an early multisport event that included a half-mile swim around Crystal Pier in Pacific Beach, a 5-mile run on the sand from the pier to the
Mission Beach jetty and back, and another half-mile swim around the pier. At the second Ironman in 1979 on
Oahu, Warren arrived as an unknown quantity from San Diego. "No one thought to challenge the saloonkeeper," wrote
Sports Illustrated's Barry McDermott. Warren ended up winning in 11 hours, 15 minutes, 56 seconds, beating out
Gordon Haller, the first year's champion. McDermott's
Sports Illustrated article featuring the three leaders in the competition, including Warren, "was Ironman’s spark," wrote
The New York Times, prompting “
ABC’s
Wide World of Sports” to cover the third Ironman the following year, with 108 athletes competing. Warren, on July 25, 1979, appeared on "
The Tonight Show" to talk with
Johnny Carson about the win. Warren has been at the start line of the Ironman Triathlon World Championship in Hawaii 20 times, finishing 16 of them. == Personal life ==
