Categories
Each race will be using Zwift Racing Score (ZRS) for categorization. We encourage you to race up a category, if your RS is at the top end of a category. Or if you simply desire an added challenge.
A: 1000 =< 690
B: 690 < 520
C: 520 < 350
D: 350 < 180
E: 180 <= 0
Your Zwift Racing Score is determined by how much success you have in races. If you place better against people with higher ZRS, then your ZRS may increase. If you place worse than people with lower ZRS, then your score might decrease. Read more about ZRS here - https://support.zwift.com/en_us/racing-score-faq-BkG9_RqrhOpens a new window
If your ZRS increases past a category boundary during the series, your points earned will not transfer to the new category with you.

Scoring
Scoring for the series will be kept on Zwiftpower. You must have an active account on Zwiftpower to be in the results.
Each race will be scored with 60 points to the winner, down to 1 point for 60th position and beyond.
Additionally there will be 2 primes per race, providing the opportunity for FTS and FAL points. Primes and prime-points will be specific to each race. Read the individual race descriptions for details regarding the primes.
All points obtained in each race are added to the series points. The person with the most series points after all the races in the series, is crowned the winner of their respective category.
The best placed 4 riders per team for each race will have their points added to the series’ Team Standings. The team with the highest points tally at the end of the series will be crowned as winner of the category.
Should a person get upgraded to a higher category during the series, their earned points for both the individual- and the team standings will remain in the lower category, and they will start earning points for the higher category in the remaining races..

RULES:
Smart trainer or power meter is required. zPower will be removed.
Heart rate monitors are compulsory for all categories.
No TT bikes unless it's a TT event.
You need to have a registered account with Zwiftpower.com and accept their terms and conditions to be in the results of the race.

Misc.
Race organizers may request riders in all categories to provide a dual recording or a matching RL effort (Strava) in order to verify a Zwift race effort. Failure to comply may result in disqualification from the event. Failure to provide a dual recording or RL effort on three requests may result in disqualification from future events, until a dual recording with a matching effort is provided.
Race organizers may exclude a rider from the results, due to poor sportsmanship. Examples may be bad language, sandbagging or other behavior of a disruptive manner.

The above information is all subject to change.
