This one hour workout is going to be some aerobic loads. But those will be punctuated by some short but very high end anaerobic efforts. The effect will be to both build endurance, but also the capacity to recruit huge amounts of muscle when generating larger watts.This one could be challenging!

ABOUT GROUP WORKOUTS Zwifters line up in the starting area just like a
normal event and once the event starts, workout mode begins. Everyone stays
together regardless of power output. That's right, if you're outputting
100W and another Zwifter is outputting 400W you will stay in exactly the
same position relative to each other. Only if you stop pedaling and fall 6
meters behind the group will the rubber-banding stop. We highly recommend
doing one of the FTP tests as the estimated FTP can be inaccurate and make
the difficulty level of the workouts too high for your current fitness
level. For more info on FTP go to:
