Zwift event guru James Bailey has spun up a new pile of iTT events to test-drive the concept of an ongoing iTT series from ZHQ, because community-organized iTT races are rather sparse lately.
It’s a weekly series that begins Monday, December 5. Event distances increase over the course of the five weeks, starting with a chaotic 4km event before ending the series with a more measured 23km.

Content-Based Clubs Test
James is also using this series to test the concept of “Content-Based Clubs” on Zwift. That is, what if clubs were formed based on the content (events) they held?

We will some crazy powers on these.
Awesome and really good times for lunch time uk too.
Nice idea but if you use the w/kg cat system itll be pointless entering unless you weigh less than 85kg
Did you mean more than 85kg? Seems like more raw power would be advantageous on most of the courses since they’re flat.
Yeah, more than 85kg*
Do we enter on Companion App for these or is there some other process?
Companion app is fine. They’re like any other Zwift event.
Wait what, a Zwift TT series without Bologna 😲
Luciano!!?
Cool! Short time-trials, count me in!
At last, let’s hope this series takes off and becomes a regular fixture beyond this trail run, with a good mix of course lengths and route profiles! \o/
Why are these Zwift events are almost always geared towards heavier riders.
Events like this and ZRLs need to include more long climbs for the lighter riders.
Equal chance of points for climbers and sprinters please.
Hi Alex, try my Mountain Massif events, they have long climbs and even short, punchy TT’s 👍
Why can B-women start again in the C-class in the races? Apparently, the men’s classification is taken again.
I just finished the first event of the Zwift TT club series. I noticed that in the D class results all the finishers were over 2.5w/kg (strictly enforced) limit? Hmmm? I’m not worried about the little finishing trophy but what’s up with that?
Thats not how the Cat limits work. Look at the results for all the CATS – every finisher will have exceeded the cat limit for their cat in such a short race.
Is it known whether this kind of iTT series will follow after finishing this ongoing one? According to the ZP, almost 1000 riders have participated so far.
I don’t know. James Bailey @ ZHQ would be the one to ask!
