Auto-Assign Race Categories

You are right on all points Gerrie.

I do feel having read some of Zwiftpower comments that the w/kg system is over
complicated and enables some riders to abuse the system.

Your second point is covered by my third quote I think? Plus…
I’m not suggesting of getting rid of Cats.

And I agree with your last point.

Auto assigning race categories would be a good start. It could be done fairly simply - first race you’re uncategorized, after that you’re assigned a category based on a statistical analysis of previous race performance. Just my two cents.


I may have misunderstood you. Sorry.
O yes, It is not the best option. Yes people does abuse it.

I agree that Zwift should auto-assign race category based on past performances. Would go a long way toward reducing those who select the wrong category based in their abilities.

O yes, and it would make racing more pleasant for lower cat racing. There a lot of new riders that will race one or two races and then give up because they think it is to hard, where in fact they are on par but 10% of the field is in the wrong cat sandbagging or not knowing how to calculate the correct cat.

I need to vent - last night I entered a race and stopped about 3/4 way through. I checked Zwiftpower interim performance stats (not sure if they were “live” while still racing or interim results) and calculated approx 80% of the 25-30 odd were in the wrong category. Example, D grader not once under 4w/kg and according to strava, frequently enters a, b, c and d grade races.

I normally dont care with the odd person getting it wrong as it can be explained (someone entering wanting a recovery ride and get caught in the racing hype, others just dont know), but last night I got my undies totally in a knot.

Grrrrrr, vent over.

And why cant I vote multiple times for these Feature requests that potentially address this issue :unamused:


The Lamb Chop Race Today 05:10

So 324 riders on Zwift power and 65 of those were DQed. that is 20% of the riders on Zwift Power were in the wrong starting pen.

There were many more riders in the race, who knows how many of them were in the wrong pen.

With races like this it is important to start in the correct pen.

Zwift Please help us out.


I completely agree that riders should be automatically entered in the correct Class depending on average race ftp (W/Kg)
I am a B Class but a lot of people with the same W/KG are entering the C Class which is why i will always end in the tail of the B Class.

@Welby_Lloyd welcome to the forum.

this topic is more for Racing, and it seem like you are talking about a group ride. Group rides does not have different starting categories. but you are correct a D group ride should be at lower watts, but different D group rides has different w/kg ranges.

Looking at the ride on Zwift power, it look like the ride leader was within the w/kg range

I would suggest finding rides that have lower w/kg requirements, to build up your power while having fun.

Thanks for the info. But how do you find that info. Everytime I look at the ride the zwift is not and easy to navigate website. Seems like I have to go to the app to get more information. But I won’t keep replying here I am obviously off topic. Thanks
