🤝 Sir Chris Hoy’s | Tour de 4
✅ Good Cause ✅ Popular ✅ Special Guests ✅ Kit Unlock
The Tour de 4 is an initiative launched by Sir Chris Hoy to change the perception of people living with stage 4 cancer and to raise vital funds for cancer charities across the UK. These rides are proving quite popular, thanks in no small part to the big-name guest riders in attendance.

🥇 KISS Racing 100
✅ Endurance Challenge ✅ Legacy Race
The KISS 100 is probably the longest-running long race on Zwift’s calendar. The A category, in particular, always has some hitters showing up!
This week the race is on 9 laps of New York’s Astoria Line 8 for a total length of 104.5km. The later timeslot (linked below) is typically the popular one, but the same event is also held at 6am UTC each Sunday.

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!
On Saturday we have Chasing Sanremo organised by ECRO, as well.
