Smaller/lighter riders are definitely disadvantaged in zwift. In real life our power is less but so is our drag coefficient so we can keep up with the bigger boys! For example in real life a small person with low height/narrow shoulders etc their lesser power would overall match the speed of someone with 80% more power but only 50% more weight.

It would be great if zwift could factor this into the modeling- there must be approximations from height/weight which translates into increased mass through the air…

please consider this, this is esp important for us girls joining group rides!
