01·Course Characteristics
A lightning-fast, flat urban course where sustained aerodynamic power and disciplined pacing against exposed winds dictate your success.
There's still hope!
The ideal build for this course is 16 weeks, and you have 11. We'll compress the essentials into your remaining time, prioritizing the demands that matter most on this course to get you to the finish line.
02·Course by Section
A freshwater swim held in Palermo Lake with a rolling start format. The lake is relatively sheltered, but winds can generate minor surface chop along the course.
A flat, non-technical, and exceptionally fast course utilizing major closed avenues and highways. The open layout leaves you fully exposed to a prevailing Southeast breeze that can create noticeable crosswinds.
A flat and fast multi-loop course snaking through the scenic paved trails of Palermo Woods and surrounding urban streets. The lack of shade on certain sections can increase thermal strain if midday temperatures rise.
03·AVG beginners' Training Timeline
This 16-week plan is specifically structured to prepare you for the high-intensity, flat profile of Buenos Aires. By emphasizing aerodynamic posture, flat-running muscular endurance, and wind-pacing strategies, you will build the durability needed to maximize speed and finish strong.
Base Aerobic Conditioning
Build baseline endurance and get comfortable with consistent swim, bike, and run volumes.
Strength & Aerodynamic Power
Develop sustained power on the bike and flat running durability to handle repetitive impact.
Race-Specific Build
Incorporate sustained aero efforts against wind simulations and simulate brick sessions at target race intensities.
Taper & Strategy Execution
Reduce training volume to shed fatigue while maintaining intensity to peak for a fast race day.
Adapts to your fitness, schedule & recovery every week.

Expect cool morning temperatures of 11°C warming to a mild 20°C by the afternoon. Use the aid stations on the run for ice and water if the sun becomes intense, as sections of the run offer little shade.
With a flat, high-intensity course, target a baseline of 90g of carbohydrates, 600mg of sodium, and 500ml of fluids per hour on the bike. Begin fueling early on the bike to prevent dehydration and cramping during the run.
Maintain a highly disciplined, steady aerodynamic effort on the bike rather than over-surging into the crosswinds. On the flat run, lock into your target race pace early and avoid starting too fast.
Prepare for an 18°C wetsuit-legal swim and opt for a versatile mid-depth front wheel to handle the Southeast crosswinds on the bike. Fly into Aeroparque Jorge Newbery (AEP) for direct proximity to Palermo.
The water temperature in Palermo Lake typically hovers around 18°C (64.4°F), which generally makes the swim wetsuit-legal for age-group athletes. While the freshwater lake is relatively sheltered, you should prepare for potential minor surface chop caused by the prevailing 6.7 m/s winds. Focus on maintaining a long, consistent stroke and take advantage of the rolling start format.
The 90 km bike course is flat, fast, and rated easy to moderate, featuring a total elevation gain of only 285 meters (935 feet) on closed avenues. However, the open highways leave you highly exposed to wind, particularly a prevailing Southeast breeze of about 6.7 m/s that can create challenging crosswinds. Success requires a highly disciplined aerodynamic posture and steady pacing rather than over-surging.
The 21.1 km run course is exceptionally flat and fast, with a negligible total elevation gain of just 12 meters (40 feet). It features a multi-loop layout through the paved trails of Palermo Woods and nearby streets, offering a highly spectator-friendly experience. Because sections of the course are fully exposed to the sun, you should monitor your thermal strain if afternoon temperatures rise toward the 20°C (68°F) maximum.
Because the flat courses encourage a highly sustained, uninterrupted intensity, you can expect high sweat and glycogen depletion rates despite the mild 11°C to 20°C air temperatures. We recommend targeting a baseline of 90g of carbohydrates, 600mg of sodium, and 500ml of fluids per hour on the bike. It is critical to begin this fueling protocol early in the bike leg to prevent dehydration and cramping on the run.
For domestic or regional flights, you should fly into Aeroparque Jorge Newbery (AEP), which is located directly adjacent to the Palermo race venue. If you are arriving on an international long-haul flight, you will land at Ministro Pistarini International Airport (EZE), which is approximately a 45-minute drive from the city center. Once you arrive, using rideshare apps like Uber or Cabify is the easiest way to travel with your bike box.
