The VirtuSlo 4Endurance Zwift League is a fun experience that I definitely enjoy. The courses and distance are well chosen, and it is always a challenge to perform well. A complete league like this is exceptional in Zwift.

After two successful seasons, I put the bike on the back burner for family reasons. The VirtuSlo 4Endurance Zwift League allows me to get back to training. I'm excited to be able to combine getting back in shape with racing and having fun.

Frequently Asked Questions
Is participation in the VirtuSlo 4Endurance Zwift League free?
Participation is completely free. All you need to do is sign up for the league using the form above and create an account on Zwift and Zwift Power.
What equipment do I need to participate?
You need a bike, a trainer, a heart rate monitor, a device to run Zwift on (computer, tablet, phone...), and the Zwift app.
In addition, it is advisable to have the appropriate cycling kit (jersey, shorts, shoes), a towel, and a fan.
Don't forget about proper nutrition — energy gels or bars, sports drink, and recovery drink.
Is it necessary to use a heart rate monitor?
Yes, all participants must use a heart rate monitor, otherwise, the result will not be recognized.
Do I have to register for each race separately via the Zwift app?
No, you only need to register for the league once through the VirtuSlo website. After that, everything is handled automatically, so there's no need to sign up for each race separately in the Zwift app.
What happens if I can't participate in one of the races?
You can skip one race without any consequences, as the best 5 results out of 6 races count towards the overall standings. The worst result will be deleted after week 3.
How are the categories determined?
Race categories are determined automatically based on your ZwiftPower vELO2 rating, which reflects your racing performance. Riders are divided into 10 categories:
- Diamond: 920+
- Ruby: 840–919
- Emerald: 760–839
- Sapphire: 680–759
- Amethyst: 600–679
- Platinum: 540–599
- Gold: 480–539
- Silver: 420–479
- Bronze: 360–419
- Copper: 0–359
Your category is determined by your vELO2 score, ensuring you're competing against riders of a similar performance level.
Is it possible to move up a category during the league?
Yes! Categories are updated automatically throughout the league based on your vELO2 rating. As your rating changes, you can move up to a higher category.
Can I switch between longer and shorter races?
You can switch from shorter to longer races at any time, but not the other way around. Once you participate in a longer race, you'll be ranked in the longer race category for the rest of the league and won't be able to switch back to the shorter race category.
Where can I see the results and rankings?
All race results will be tracked on the Zwift Power website. The overall league standings will be published on the VirtuSlo website.
Where can I find the detailed league rules?
Detailed league rules can be found on the VirtuSlo website.
