WHAT IS CATEGORY ENFORCEMENT?

Category Enforcement will prevent Zwifters from entering a category they are not eligible for. Our goal is to increase fairness in racing.

HOW DOES IT WORK?

- Zwift checks a racer's past performance using VO2 max and FTP to determine their race category.
- Racers can join a category at or above their category. For example, if you are "C" category, you can race in C, B, or A category. You can not race in the D category.

Welcome to the DIRT Dadurday Chase Race.

Race category starts will be staggered with the D category starting first, and each C, B, and A category starting later.

The riders will be challenged to work together using the draft, and group tactics in order to catch the category ahead of them while also holding off the categories that started after.

Races will have 4 power-ups enabled with equal odds (25% each):
draft, feather, burrito, & ghost!
Compete with the best, and see how you stack up!

You must be opted-in on Zwift.com & ZwiftPower.com to be counted for race results.
We highly encourage A racers to follow Zwift eRacing Ruleset.
