🥇 The Pink Cheetahs Social Ride 💕 🐆

✅ Women-only  ✅ Popular event

Join the Pink Cheetahs for a women-only group rides around the roads of Urukazi. The goal of this ride and the Pink Cheetahs club as a whole is to bring more women into the sport of cycling. This ride does not have any leaders assigned, but there are numerous highly experienced Zwifters registered for the event. Because the ride is a category E ride, riders are free to go at their own pace.

This 60-minute social ride will take riders on the Island Hopper course—a course that covers almost all of the roads of the Urukazi expansion.

🥇 DBR SufferDay League VIII

✅ Tough Race

For the past few months, DBR has been hosting their SufferDay League VIII. This is an endurance race series where Zwifters convene each weekend to battle against some of the best riders in each category. The series is based on points, so be ready to sprint when riders go for the FAL and FTS points at each segment!

To be included in the final results, riders must comply with the ruleset in the event description. These rules help the event remain very competitive.

This week’s course is relatively flat, taking place on 4 laps of the Turf N Surf course in the Makuri Islands.

🤝 Seattle Baby Steps 1.0-1.3 w/kg

✅ Beginner Friendly

Looking for a welcoming group ride? The Seattle Baby Steps 1.0-1.3 group ride is the perfect group ride for beginners. This group ride welcomes all riders—whether they are newer riders, younger riders, older riders, or just riders looking for recovery, all are welcome.  

Since the group ride is geared towards riders who are looking to ride in the 1-1.3 w/kg range, the ride will be taking place on the Sprinter’s Playground course. This course features a relatively flat elevation profile with a few climbs scattered throughout.

How We Make Our Picks

We choose each weekend’s Notable Events based on a variety of factors including:

  • Is the event unique/innovative in some way?
  • Are celebrities (pro riders, etc) attending/leading?
  • Are signup counts already high, meaning the event is extra-popular?
  • Does the ride include desirable unlocks or prizes?
  • Does the event appeal to ladies on Zwift? (We like to support this under-represented group!)
  • Is it for a good cause?
  • Is it just plain crazy (extra long races, world record attempts, etc)?
  • Is it a long-running, popular weekly event with a dedicated leader who deserves a shout out?

In the end, we want to call attention to events that are extra-special and therefore extra-appealing to Zwifters. If you think your event qualifies, comment below with a link/details and we may just include it in an upcoming post!

Okay, these new checkbox highlights with what makes each interesting is awesome! Thanks!

I’ve been checking out the “Sweet Unlock” ones in particular. That’s exactly what I’ve looking for. (Does that make me a virtual biking clothes horse?)

Thanks again.

Chasing Series 2023 is rolling on with the classics!

First race in the classics point series (before the grand tours start…) is Chasing Saxo. 2 time slots have already raced this morning, but there are two more today at 1900UTC and 0100UTC

Sunday is Chasing Wevelgem with 4 time slots available – links here:

Looks like just under 500 people will race it today (!), including Julien Bernard from Trek Segafredo randomly showing up 🙂

Yeah – I love the rotation and wouldn’t keep putting it in the main section either, any organizer trying new stuff, emphasizing different stuff should get some sunshine I think, not that my opinion really matters :-). I just wanted to throw the links in the comments in case folks were interested. Cheers Oli

looks like the castelli fondo has a mixed up starting time. link from you states 10:25AM CET, but in the events list on zwift website, there is nothing under the jerseyunlock tag, and in the full events list it is listed as 11:00AM CET, but clicking on that from the list again states 10:25AM CET. Might affect the number of participants, especially if it does start early and people plan for late start. Anyway, thanks for the find =)

I woke up early here on the East Coast for this one and completed the Gran but never received a jersey in game. Did anyone else get the jersey? Do you need an unlock code to get it?
