01·Course Characteristics
A flat, fast, and highly exposed course along the Paraná River. Success in Encarnacion requires managing wind on the bike and preparing for intense solar exposure on the run.
There's still hope!
The ideal build for this course is 16 weeks, and you have 12. 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 single-loop swim starting and ending at the popular San Jose Beach. The water is generally calm, but light river currents and chop can develop if the wind picks up from the south.
A fast, two-loop course utilizing the wide boulevards of the Costanera and extending onto Route 1. The profile is mostly flat with some rolling sections, but completely exposed to the elements.
A multi-loop run entirely along the Costanera, offering beautiful river views but zero shelter from the midday sun. The support from local crowds is fantastic, but the concrete absorbs and radiates heat.
03·AVG beginners' Training Timeline

Expect temperatures to rise quickly by midday, reaching 27°C with high humidity. Dump water over your head at every single aid station along the Costanera and wear a white, breathable race kit to reflect the intense solar radiation.
Aim for 80-90g of carbohydrates and 700-1000ml of fluids per hour on the bike to counter sweat losses from the humidity. Carry handheld bottles or use on-course hydration early on the run before dehydration sets in.
Do not over-cook the flat bike course; holding a steady, disciplined power output into the headwinds will save your legs. On the run, start conservatively on the first loop and let the flat terrain help you build momentum.
A deep-section rear wheel is highly recommended for the flat bike course, but choose a moderate front depth to handle river crosswinds. Arrive at least two days early to adapt to the Paraguayan spring humidity.
The swim takes place in the Paraná River, where water temperatures in mid-October typically average around 22°C (72°F). Under World Triathlon rules, this means the swim is highly likely to be wetsuit-legal, which provides excellent buoyancy. However, you should still prepare for the possibility of a non-wetsuit swim if unseasonably warm weather occurs close to race day.
The bike course in Encarnación is generally fast and flat, making it ideal for athletes looking to maintain a consistent aerodynamic position. While the total elevation gain is minimal, you should prepare for potential wind exposure along the open coastal roads of the Costanera. Focusing your training on sustained sweet-spot intervals will help you excel on this rolling, non-technical terrain.
October in Encarnación brings spring conditions, with average daily high temperatures hovering around 26°C (79°F) and high humidity levels. While the mornings are usually pleasant for the swim, the run course can feel quite warm as the sun gets higher. Proper hydration planning and heat-acclimatization training are essential to managing your core temperature during the half-marathon.
Yes, the run course is exceptionally flat as it traces the scenic Costanera alongside the Paraná River. This multi-lap layout features minimal elevation change, allowing you to lock into your target half-marathon pace. However, the lack of shade along the riverfront means you will be highly exposed to the midday sun, making sunscreen and cooling strategies critical.
You should aim to arrive in Encarnación at least three days before the race on October 11, 2026. This allows you ample time to check in, complete your practice swim in the Paraná River, and adapt to the local humidity. Arriving early also ensures you can scout the transition areas and resolve any mechanical issues with your bike before race morning.
