Tríade — Circuito Paulista (São Bernardo do Campo)

The water of the Represa Billings presents a steady, freshwater environment where the absence of tidal currents allows for a predictable stroke rhythm. In late August, the surface remains generally calm during the early morning, though swimmers should anticipate light afternoon breezes that can create small, rhythmic ripples across the wider sections of the reservoir. Unlike coastal events where saltwater buoyancy aids the body position, this inland basin requires a deliberate engagement of the core to maintain a high glide throughout the distance. The reservoir serves as a primary water source for the São Paulo metropolitan area, and its expansive, winding arms provide a technical challenge in sighting as you navigate between the vegetated shorelines and the open channels of the ABC region.

Race day logistics

Organized by Igor de Souza’s Maratona Aquática circuit, the Tríade event scheduled for August 29, 2026, focuses on endurance pacing within this controlled lake environment. Participants receive a timing chip, an event cap, and a finisher medal upon completion. The logistics are designed to accommodate the influx of swimmers from the nearby industrial hub, with the start area set up to manage the entry into the water efficiently. Because the reservoir is massive and spans multiple municipal borders, the course utilizes specific, buoyed segments that avoid the more constrained industrial zones, ensuring a clear path for athletes. Swimmers looking to maintain their training consistency throughout the year often compare these conditions to other lake-based sessions in the São Paulo state circuit, noting the necessity of adapting to the slightly cooler freshwater temperatures common during the tail end of the winter season.
