Pack Dynamics V5 update [July 2025]

I noticed yesterday riding with Maria that the majority of the group was in the center of the road, not sure if this was meant to fix that?

So, it seems we’re back to cheating players again. Those with steering enabled are once again constantly pushed aside, riding to the left or right of the group. You claimed to have tested this for months lmao but we’re right back where we started, screwing over everyone using steering. Zwift, you should truly be ashamed of yourselves.

From a quick look, groups do seem to ride in a narrowed centre position on the road.

Is this not going to open up supertuck on descents (when doing >57kph and >3% descent gradient) for those with steering on the left and right, but alongside a group?

If it is significantly better/different wouldn’t it be Pd6

Unless there are differences in the behaviour depending on which steering devices you have, then absolutely right, I’m using Kickr Bike and get shoved to the side (and out of the pack) all the time and then steering back is very sluggish.

Also steering away from the pack (so you can overtake without blocking) is similarly very slow until you get about 1 bike width away and ā€œescapeā€ the steering restrictions.

I know I should video the entire 1.5 hour Constance group ride to prove this happens, but it does.

Also way easier to overtake out of the draft, you don’t need to use as much power. The difference in the lack of ā€œblockingā€ between in the draft of other riders (blocked) and out of it (no blocking) is pretty big. The blocking effect really needs to be reduced.

Not to say the system isn’t broken but why are you not tailing the group 2-3 meter as one of the last guys for best draft?

Pack Dynamics still seems off. When doing a race with steering disabled, several of us had the issue of constantly getting pushed to the centerline and out of the draft. It has been a huge issue during the ECRO races.
I also notice that the behavior of the blob is and has been unrealistic on descents. Its like zwift is taking the weight of the entire group to determine speed. If a chasing riding is putting out more power on the downhill than the lead group rider that is cutting the wind, they should be catching up, not falling further behind.

This makes sense. I thought I was lagging, it’s quite annoying.

I completely agree that the blocking needs to be reduced. The rider in front slows down or leaves a gap. You push harder to stay with the group, but you just get stuck behind. Then they suddenly he speeds up and ride away, leaving you in the dust!

There is a balance though because this happens all the time when racing outside.

But that’s not because an algorithm is putting a virtual block on you, that’s because you physically cannot do more power to move forward or on tge other case you’d crash into the person in front.

In Zwift, it’s just a computer function saying that regardless of the power you a putting out, you’ll be blocked from going forward, and the rider behind will push you to the side as well, for added fun.

I spent 1.5h today with the Constance group getting pushed from one edge of the road to the other like a pinball. Disabling steering from the pairing screen didn’t seem to help. I frequently got left out at the side of the road.

I just teleported multiple times back to the robopacer to avoid fighting that. That also avoided the blocking effects.

These things have all been reported for a long time by others so reporting again here probably won’t achieve much.

I understand the frustration but it’s possible to break the draft in zwift and it’s possible to sprint around a rider leaving a gap in real life.

They haven’t got the balance right but the idea that if someone slows up you should just drift through them isn’t the answer.

The real fun is when people start to realise you can break the draft on a single rider by stopping pedalling for a few seconds.

To me it feels perfect I have done 2 races and 10h weeks robopacer and it feels spot on. Good job.

I think that people need to learn how to move in a group.

I’ve seen you mention that before here and elsewhere and I tried it after reading it a few times. I suffer from being bullied out of the pack a lot, perhaps seeking some tiny draft from a side rider instead of nestling in to the pack draft. Also getting gapped off occasionally. So I’d like to figure it out, can you describe precisely what you do and what the goal is?

Seemed like the goal is to reset the draft-seeking / center-seeking so it finds stronger draft vs following someone to the side or sitting out there alone, is that correct? And what I tried was to stop pedaling completely for around 3 seconds of zero watts, but, it didn’t seem to work.

I’ve got Play controllers currently paired and steering available but would like to be able to just sit in a group on Tempus in the draft without requiring steering input. Seems like a simple goal but is somehow impossible at the moment.

Holy hell. This still has not been fixed?! @James_Zwift Come on guys. We’ve been complaining about this for more than a year. You know this is unfair for people without steering. What’s the excuse for not fixing this?
