Beach to Bay Relay Marathon is the largest relay marathon in the United States, held annually in Corpus Christi, Texas since 1976. The six-leg, 26.2-mile course starts on the sands of North Padre Island, cuts through Naval Air Station Corpus Christi, and finishes at McCaughan Park, drawing over 16,000 runners plus another 16,000 spectators. Held every third Saturday in May as a tribute to the U.S. Armed Forces, the race pulls athletes from across the country and internationally, including Kenya, England, and Mexico. The event generates nearly $3 million in regional economic impact, giving sponsors high visibility among a dedicated running community plus significant local media coverage, deep integration into one of Corpus Christi's largest annual events.
