Where You Finish Counts

South Padre Island, the Sandcastle Capital of the World, is now home to the ultimate Runcation weekend! The SPI Marathon and Half-Marathon begin at the historic Port Isabel lighthouse, crosses the crystal waters of the Laguna Madre, via the 2.5-mile Queen Isabella Causeway, to the sun-soaked shores of South Padre Island. White sand beaches, sandcastles, palm trees and enthusiastic spectators line the route to your finish line at the largest beach bar in Texas!

South Padre Marathon

A scenic, flat course (only one hill in the entire 26.2 miles!) with sights and sounds that can only be found in South Padre, the perfect race for getting your qualifying time or setting a new personal record.

South Padre Half Marathon

This scenic, flat course (only one hill in the entire 13.1 miles!) is perfect for the first timer, the long timer, and the “I’m only gonna do this once” timer! Whether your goal is to check off a bucket list item, set a new personal best time, or simply enjoy a run in an Island paradise, this event has it all!

Half Marathon Relay

Grab two of your running buddies to create a team for the 3-Person Relay. Each person will complete 4-6 miles on the Half Marathon course. Relay participants will receive the same half marathon swag as the full half.
