The star of the show

The South Beach Triathlon course begins with an ocean swim in the beautiful, warm water (expected water temperature is 78 degrees) that runs parallel to world-famous South Beach. The bike course is relatively flat, crossing over Miami Beach’s famous causeways with scenic views of the Intracoastal Waterway, downtown Miami and Miami Beach. The run course will be a fast out and back alongside Miami Beach’s Art Deco District, finishing on the white sands of South Beach.

Relay Transition Area

A designated relay area is available near the run out area of the transition. Relay teams use this area for both transitions. Swimmers meet their biker in the pen. Biker runs to their designated bike rack, puts on the timing chip and exit. Upon return, biker racks their bike and meets their runner in the relay pen. Runner then exits to complete the race.

Aid stations
There are water and Gatorade at all stations along the course and at the start and finish lines. All aid stations on the course have dozens of enthusiastic volunteers and portable toilets located nearby.

Gatorade Endurance is proud to partner with the South Beach Triathon to help fuel runners to the finish line. Grounded in years of hydration and sports nutrition research, Gatorade Endurance products are developed to meet the specific needs of endurance athletes.

Gatorade Endurance Formula
Gatorade Endurance Formula will be on course at every aid station. With nearly double the sodium and triple the potassium of original Gatorade Thirst Quencher, Endurance Formula is a specialized sports drink designed to hydrate athletes engaging in prolonged training and racing when fluid, electrolyte and carbohydrate losses can be significant.
