PRL on Zwift: Understanding the Paris-Roubaix Loop Challenges

What is PRL on Zwift?

On Zwift, "PRL" refers to the "Paris-Roubaix Loop" challenges, specifically the "PRL Full" and "PRL Half" routes, which are significant virtual endurance achievements on the platform's London map, inspired by the iconic professional cycling race.

Understanding "PRL" in Zwift

The acronym "PRL" stands for Paris-Roubaix Loop. This designation within Zwift's virtual cycling world pays homage to the legendary real-world Paris-Roubaix professional cycling race, known for its arduous cobblestone sections and demanding endurance requirements. On Zwift, the PRL routes are among the most challenging and sought-after badges of achievement, located within the virtual London map. They test a rider's physical and mental endurance over significant distances and elevation gains.

The PRL Full Challenge: An Endurance Feat

The PRL Full is Zwift's ultimate endurance badge for the London map, designed to simulate a monumental ride. It is not merely a single loop but a cumulative challenge that requires riders to complete multiple laps of specific London segments.

• Route Composition: The PRL Full combines elements of the London Loop, Classique, and Surrey Hills routes. Riders repeatedly traverse sections of the London Loop, including the Box Hill climb, until the total distance and elevation requirements are met.
• Key Metrics:
  • Distance: Approximately 173 km (107.5 miles)
  • Elevation Gain: Approximately 2330 m (7644 ft)
• Time Commitment: Depending on a rider's fitness and pace, completing the PRL Full can take anywhere from 5 to 9 hours, making it a substantial time investment and a true test of stamina.
• Significance: Successfully completing the PRL Full earns riders a coveted badge, signifying a high level of endurance and dedication within the Zwift community.

The PRL Half Challenge: A Stepping Stone

For those not yet ready for the full monumental effort, the PRL Half offers a more accessible, yet still challenging, endurance goal. It follows a similar structure to the PRL Full but with reduced distance and elevation.

• Route Composition: Like its full counterpart, the PRL Half involves repeated laps of sections within the London map, focusing on a scaled-down version of the endurance challenge.
• Key Metrics:
  • Distance: Approximately 69 km (43 miles)
  • Elevation Gain: Approximately 930 m (3051 ft)
• Purpose: The PRL Half serves as an excellent stepping stone for riders looking to build their endurance, test their nutrition and pacing strategies, and prepare for the eventual undertaking of the PRL Full. It still awards a badge upon completion.

Why Undertake the PRL Challenges?

Engaging with the PRL challenges offers numerous benefits for cyclists and fitness enthusiasts:

• Physical Endurance Development: These long-duration rides are excellent for building cardiovascular fitness, muscular endurance, and improving the body's ability to utilize fat for fuel.
• Mental Fortitude: Tackling such extensive distances requires significant mental discipline, focus, and resilience, teaching riders to push through discomfort and maintain motivation over many hours.
• Achievement and Community: Earning the PRL badges provides a strong sense of accomplishment and allows riders to join an exclusive group within the Zwift community who have conquered these demanding routes.
• Training Simulation: For outdoor cyclists, the PRL challenges can simulate the demands of long-distance events, sportives, or even multi-day tours, providing a controlled environment to practice pacing, nutrition, and hydration strategies.
• Structured Goal Setting: They provide a clear, measurable goal that can structure training plans and provide motivation for consistent effort.

Preparing for a PRL Challenge

Success on the PRL routes, particularly the Full, requires thoughtful preparation:

• Gradual Progression: Do not attempt a PRL Full without first building a solid base of endurance. Gradually increase your weekly mileage and the duration of your long rides.
• Nutrition and Hydration Strategy: Practice your fueling strategy on shorter long rides. Understand what types of carbohydrates, electrolytes, and fluids work best for you to prevent bonking or dehydration.
• Bike Setup and Comfort: Ensure your bike fit is optimized for long hours in the saddle. Check tire pressure (if using a smart trainer, ensure proper setup), and calibrate your power meter or smart trainer for accurate data.
• Mental Preparation: Break the ride down into smaller, manageable segments. Visualize success and prepare for moments of discomfort. Having a playlist, podcast, or a Zwift group ride can also aid mental engagement.
• Pacing Strategy: Plan your power output or effort level. Starting too fast is a common mistake that can lead to early fatigue. Aim for a sustainable effort you can maintain for hours.

Tips for Success on the PRL Route

Executing a successful PRL ride involves more than just physical readiness:

• Pacing is Paramount: Resist the urge to go out too hard, especially on the initial laps. Maintain a steady, sustainable effort that you know you can hold for the entire duration.
• Consistent Fueling: Don't wait until you're hungry or thirsty. Set an alarm to remind you to eat small amounts of carbohydrates (gels, bars, fruit) and drink fluids regularly, typically every 15-20 minutes.
• Break Up the Ride Mentally: Focus on completing one lap at a time, or even just reaching the next climb or descent. This makes the overall distance seem less daunting.
• Utilize Drafting: If riding with others or in a group event, leverage drafting to conserve energy, especially on flatter sections.
• Listen to Your Body: Pay attention to any signs of fatigue, cramps, or discomfort. Don't be afraid to take a short break off the bike if needed, or adjust your pace.
• Enjoy the Experience: While challenging, remember to appreciate the virtual scenery, the sense of community, and the personal journey of pushing your limits.
