Zwiftpower Category Limits?

Can someone please link to, or simply explain the category limits of zwiftpower? I am finding it difficult to find an explanation/page published by zwiftpower (the source) themselves? finding lots of posts from third parties relaying information, but nothing from the source? Zwift uses zMAP and zFTP, but what the heck is zwiftpower using as a proxy? To avoid being disqualified from an event, for example Exceeded category power limits (WKG), it would be helpful to actually know what the limits are first (simply written in a table as zwift does with zMAP and zFTP)! it is clear that zMAP and zFTP are only being used to define categories whilst another calculation is used for “category limits” for races. Guessing 20min power is being used somehow, but as a climber/tempo rider that beckons the question why? or maybe those with good 5 min, 1min or even 15 second power can also exceed category power limits?

I thnk the majority of races now don’t use the WKG limits as set in zp they are using Cat enforcement in that if you entered as the right cat you are ok to continue.

Unlike the old zp cats it only takes 1 race over power to get upgraded so the impact is less.

There proably is a zp forum post somewhere explaining what the WKG limits are but it’s been a while since ive seen a race oragniser user them.

I got WKG on Wednesday

fair enough a lot don’t use the WKG any more but 4.5 20mins would usually put a rider in A as you have been now prompted so at least it was for only 1 race.

cheers! 1. the event organizer can decide on WKG enforcement or not for a specific event? 2. but still where is the definition from zwiftpower for WKG. How is it calculated? why is this information not easy to find!

You can probably ignore the old ZwiftPower Category limits or how they were calculated as they are almost certainly redundant. If you wish to see them click the ‘Help’ tab on the ZwiftPower home page.

If you want to view the new Category Enforcement (CE) category limits check link below:

Since the change from ZwiftPower to CE there have been some issues where WKG disqualifications have been issued. Mostly this has been where Clubs have been permitted to run non CE governed races and then apply disqualifications to anyone exceeding the race entry limits, usually by more than 0.2wkg.

As Gordon has suggested if a race is being run under CE regulations then the rule should be - If you are able to enter the category you will NOT be disqualified for exceeding the category limits [but hopefully you will be upgraded as a result of your new power, as you have been].

To some extent Clubs run races and are fairly free to impose and enforce their own rules.

The recent race where you received a WKG is a slightly odd one. It looks like it is either by invitation or you must be a member of a Norwegian Club. (I can’t find it on ZCA).

Their rules, in Norwegian, suggest that it is run under Category Enforcement (as I can’t find it on ZCA I’m unable to confirm if has been set up as CE) but rules also mention DSQs.

I’m not sure how this WKG has affected your position in a series of races. If it is of major concern to you it is something you may need to take up with the Club rather than Zwift.

If you want to read forum threads just type Category Enforcement into the search facility top right of forum page. There will be plenty to read but you, possibly, will be none the wiser.

Hopefully soon CE categories will be replaced by a results based system.

thanks for the reply! both Ian and Gordon. Sounds correct, and something they are sorting out, the entire top 10 for a climbing event got WKG based on 20 min power (though all were well under limits for the entire event) :). The lack of clarity is a problem for riders, with event organizers applying different rules makes it even more so. Hopefully the new system fixes this and zwiftpower publish an easy to find definition for each showing clearly upper and lower limits. The present system is like getting a speeding ticket when you cant see what the speed limit is :slight_smile:
