02·Course by Section
A single-loop swim in the highly sheltered, historic basin adjacent to the Chateau de Versailles. Enjoy completely flat, chop-free water and zero current, making this one of the most beginner-friendly swims on the circuit.
A single 90 km loop that journeys into the rolling, forested hills of the Chevreuse Valley, featuring high-quality asphalt roads interspersed with urban roundabouts and speed bumps. Prepare for two main climbs, including the 1.5 km Cote de la Vacheresse, balanced by fast, flat plateaus.
A 21.1 km half marathon split across 3.5 loops on a flat but physically punishing mixed terrain of paved paths, hard-packed dirt, concrete, and historic cobblestones. The course offers almost no shade, fully exposing you to the mid-summer sun and afternoon heat.

With peak temperatures averaging 24 to 26°C and potential heatwaves exceeding 30°C, cooling is critical. Utilize every aid station to douse your head and body with cold water to manage your core temperature. SPF protection and a light, white running cap are non-negotiable for the fully exposed run.
Leverage the flat sections of the bike leg to strictly consume 60-90g of carbs per hour using Maurten gels and drink mixes. Increase your sodium and fluid intake to offset heavy sweating in the July heat. Do not skip any aid stations on the run, even if you feel fine early on.
Swim smoothly to save energy, then ride conservatively on the early climbs like the Cote de la Vacheresse to keep your heart rate in check. Save your legs for the run, where the uneven cobblestones and high heat will rapidly accelerate fatigue if you overpace the bike.
Bring a TT bike or road bike with clip-on bars to exploit the fast flat plateaus. Prepare for the European 'clean transition' system by organizing your gear into the designated Blue and Red bags. Plan to stay locally in Versailles to simplify your race morning logistics.
The course is rated as a moderate 3 out of 5 in difficulty, combining a very beginner-friendly swim with a rolling bike and a mixed-terrain run. While the swim in the calm Piece d'Eau des Suisses is highly sheltered, the run is physically demanding due to high summer heat, cobblestone sections, and a multi-loop format. Proper pacing on the bike's climbs and a disciplined hydration strategy are essential to conquering this race.
The single-loop 90 km bike course features a total elevation gain of approximately 620 to 800 meters (2,034 to 2,624 feet) as it winds through the Chevreuse Valley. While you will encounter fast plateaus, you must also navigate forested rolling hills and two key climbs, including the 1.5 km Côte de la Vacheresse which averages a 4.6% gradient. Either a TT bike or a road bike with clip-on aerobars is highly recommended to handle this varied terrain.
The 1.9 km swim takes place in the historic Piece d'Eau des Suisses, where the freshwater reservoir is highly sheltered, offering calm, chop-free water with zero currents. Water temperatures typically hover around 21°C (70°F), meaning wetsuits are usually legal, though they could become optional if the water exceeds 24.5°C. The race uses a self-seeded rolling start format to ensure a smooth flow of athletes into the water.
The 21.1 km half marathon consists of 3.5 flat loops with about 100 meters of total elevation, but the terrain itself is highly mixed and technically challenging. You will run on a combination of paved paths, concrete, hard-packed dirt and gravel trails, and historic cobblestones near the palace. The route along the Piece d'Eau des Suisses and Avenue de Paris offers very little shade, exposing you directly to the peak mid-summer heat.
Versailles is located 20 km southwest of central Paris and is easily accessible via a 35 to 40-minute ride on the RER C train, though staying locally in Versailles is highly recommended for stress-free race morning logistics. Please note that this European event utilizes a 'clean transition' system, meaning you will store your gear in designated Blue and Red transition bags rather than placing it next to your bike. Additionally, be prepared for hot July temperatures averaging 24°C to 26°C (75°F to 79°F), which demands a strict nutrition strategy featuring high sodium and fluid intake.
