Zwift Cracks Down on Unfair Play with New Category Enforcement Rules
Virtual racing platform Zwift implements category enforcement to ensure a level playing field, preventing riders from entering unauthorized race classes.
Zwift is leveling the playing field with a new policy: Category Enforcement. This system stops cyclists from joining race categories they aren’t qualified for, aiming to boost fairness in virtual competitions.
- Zwift’s Category Enforcement prevents riders from entering ineligible race categories.
- The system uses VO2 max and FTP data to determine a rider’s category.
- Riders can join categories at or above their assigned level.
- Mandatory equipment includes heart rate monitors and power meters or smart trainers.
- Riding in an incorrect category can lead to disqualification.
Zwift’s Category Enforcement is designed to ensure a fair race environment by preventing participants from entering categories for which they are not eligible. This new system checks a racer’s past performance, specifically their VO2 max and FTP (Functional Threshold Power) figures, to assign them to an appropriate race category.
How Category Enforcement Works
Under the new rules, riders are assigned a category based on their performance metrics. For instance, a cyclist designated as a “C” category rider can compete in “C,” “B,” or “A” categories. However, they are prohibited from racing in a category below their assigned level, such as “D.” This ensures that races are populated with participants of similar abilities.
Race Requirements for Fairness
The platform emphasizes the need for accurate data to maintain fair competition. To participate in races, riders are required to:
- Register on zwiftpower.com and agree to data sharing conditions for official results.
- Wear a heart rate monitor.
- Use a power meter and/or smart trainer.
- Select the appropriate race category for their ability.
Failure to adhere to these requirements, particularly riding in an inappropriate category, can result in disqualification.
Specific Race Rules and Categories
Additional rules are in place to uphold the integrity of the races. These include:
- Prohibition of “zPower” riders (riders using uncalibrated or basic trainers).
- Mandatory use of heart rate monitors for all participants across all categories.
- Adherence to 5-minute and 20-minute CEVAZ limits, with riding in the wrong category leading to disqualification.
The defined race categories are as follows:
- A: 4.0 W/kg to 5.0 W/kg
- B: 3.2 W/kg to 3.99 W/kg
- C: 2.5 W/kg to 3.19 W/kg
- D: Under 2.49 W/kg
These categories aim to create a structured and equitable environment for all virtual cyclists.
