“Rolling with ENVE” ZRacing Series Details (September 2025)

Zwift’s “ZRacing” is the platform’s most popular ongoing race series, and in September, the series teams up with ENVE for a wheelset worthy of the spotlight!

Read about this month’s race routes below, along with more on the ENVE SES 4.5 PRO wheels, including the real-life giveaway.

New ENVE Wheels

The new ENVE SES 4.5 PRO wheelset makes its in-game debut in September’s races, with every rider automatically placed on these wheels for each event. Word is these wheels are fast, and Zwift says this month’s courses were chosen “to showcase their all-round dominance.”

It’s not just marketing hype, either: the IRL wheels were developed with direct input from Tadej Pogačar and UAE Team Emirates XRG over two seasons, and this year they amassed 25+ victories before Tadej won the Tour de France! They’re lighter and more refined than the standard ENVE 4.5, including new hub and bearing technologies.

Learn how these wheels perform on Zwift >

You can test the new wheels for free in September’s ZRacing, then head to the Drop Shop whenever you’d like to buy them:

Complete any stage for a shot at winning a real-life set of the new 4.5 PROs in ENVE’s official prize draw! (Zwift will send an email with an entry link…)

GC Leaderboards

Zwift’s web-based leaderboards are used for tracking the monthly GC competition for the ZRacing series. No ZwiftPower registration or use is necessary.

Access the ZRacing leaderboards at zwift.com/racing/zracing >

Your GC ranking is based on your best finishing time for each stage, and you can race each stage more than once to try for a better time.

Category Options

Zwift schedules three different flavors of ZRacing events in order to encourage “Fairer, more competitive racing for everyone.” They each use different racing score ranges for categorization and are titled Advanced, Range 1, and Range 2. Click banners below to see upcoming events for each:

Extras

Get the Badge

Each month’s ZRacing series has a unique achievement badge, which you can unlock by finishing every stage for the month. There are no makeup events, so if you miss a stage, you miss out on the badge and competing in the GC.

One and Done

Zwift has planned these events to deliver a solid 1-hour workout, so each race should only take around 1 hour to complete, including your warmup and cooldown.

I think the link to the GC leaderboard is incorrect: /zwift-games-leaderboards/ (points to Zwift Games). I’m guessing it should be /racing/zracing

Correct. It’s limited to US, Canada, EU, Switzerland Norway, and the UK.
But thanks zwift for sending me an email saying I’ve got a chance to win

With everyone using Enve wheels, does this mean that the Tron bike isn’t allowed? All that Tron upgrading wasted for this month of racing I guess

If on a halo bike, which bike do we get forced on and which bike does get the mileage credit for upgrades?

it’s a good question. My guess is that no one really knows until we see what happens on Stage 1 later today. Probably a good idea to hit the pens early to make any frame adjustments though!

Turns out I just stayed on my P74 and mileage was added to P74 as well.
I did get the email inviting me to subscribe to enve to enter the raffle.

If the courses are suited to these wheels, the Tron bike is not a good choice anyway then.

What’s the point of the steamroller power up on two bridges loop? I thought it was all road. Is there some gravel?

The wooden bridge and the cobbles through the Italian Village have slightly increased rolling resistance, the Steamroller will do something there. But it won’t be at all decisive in the race

@Eric Schlange, if you accidentally start one of these races on a gravel bike, does Zwift somehow switch you to these wheels? Asking for a friend 😕

Makes sense… I’ve never been dropped so early into a race as I was today. Er.. I mean, my friend has never been dropped so early into a race.

Another thumbs down for excluding the southern hemisphere, disappointing

I would like to see a bike/wheel trade in program in the future.

I see lots of people posting they got the email for the sweepstakes. I did all of the stages and never got anything. I checked my spam folder. I assume chances are near zero, but kind of weird as I get other emails from Zwift but nothing for this.
