The 31st annual GCT will be May 11, 2013! What began as an economic development idea has grown into the best long-course triathlon in the Southeast. Each year, 1500 triathletes converge on Panama City Beach and test their strength with a 1.2 mile swim in the Gulf of Mexico, 56 mile bike through Bay County, and a 13.1 mile run in residential neighborhoods in PCB.
