🤝RAD RACE VO2 max Booster Plan – Week 2 – Group Ride

The folks at Rad Race have organized a 12-week structured workout series on Zwift. Goal: To improve maximum oxygen uptake (VO₂max) – the basis for sustainable performance development on the bike.
See the series homepage and details >
Saturday’s group ride isn’t a structured workout, but rather an endurance group ride: 3 hours at 2-3 W/kg on France’s flat R.G.V. route. Rad Race says the goal of the ride is to “Build your aerobic base – the foundation for all training zones. Perfect for active recovery and balancing out your VO₂max week.”

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!
