Mack Cycle Tri-Miami Triathlon Trilogy : General information
The Mack Cycle Tri-Miami Triathlon Trilogy is a three race series held on Key Biscayne near downtown Miami. The 2026 dates are May 17, June 21, and August 9, and the venue is Crandon Park. Events are spaced about six weeks apart.
Distances and event types include:
- Sprint Triathlon (S 500 m, B 14 km, R 3.3 km) - 1/3 Olympic Distance
- Sprint Duathlon (Run 1.5 km, Bike 14 km, Run 3.3 km)
- Sprint Aquabike (Swim 500 m, Bike 14 km)
- Intermediate Triathlon (S 1 km, B 27 km, R 6.7 km) - 2/3 Olympic Distance
- Olympic Triathlon (S 1.5 km, B 40 km, R 10 km)
- Olympic Aquabike (Swim 1.5 km, Bike 40 km)
The swim takes place in a calm area of the Atlantic Ocean. The bike course departs Crandon Park and climbs the William Powell Bridge, which has a steady 4% grade up to about 76 feet, then returns across the bridge; the rest of the bike course is flat. Lapping formats are used: Sprint one lap, Intermediate two laps, Olympic three laps.
The run follows paved trails through Crandon Park alongside the ocean and passes shaded areas. The series combines multiple historic Key Biscayne triathlons into one three race format. Visit the organization's website for the most recent information.
